Answer:

25.12 m (or 25.13 m)

Step-by-step explanation:

Recall the formula for the circumference of a circle:

[tex]2\pi r[/tex]

where r is the radius.

We are given that the radius is 4 m, so let's plug that into our formula:

[tex]2\pi r=\\2\pi *4=\\8\pi[/tex]

[tex]\pi[/tex] is approximately 3.14, so let's multiply 8 m by 3.14. We get:

25.12

So, the circumference is about 25.12 m.

(if you multiply by pi itself using a calculator, the answer is about 25.13 m)

Answer:

The lateral area of a cone is given by the formula:

L = πrs

Where r is the radius of the base, s is the slant height, and π is pi.

We are given that the lateral area L is 587π cm^2 and the radius r is 32 cm. Substituting these values into the formula, we get:

587π = π(32)s

Simplifying, we can cancel the π on both sides of the equation:

587 = 32s

Dividing both sides by 32, we get:

s = 18.34375

Rounding to the nearest tenth, we get:

s ≈ 18.3 cm

Therefore, the slant height is approximately 18.3 cm.

Answer:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where A is the future value, P is the present value, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time period in years.

(a) To find the present value of the money, we need to solve for P in the formula above. We are given that A = $3000 and t = 18/12 = 1.5 years. The interest rate is 6% per year, compounded monthly, which means n = 12. Substituting these values into the formula, we get:

3000 = P(1 + 0.06/12)^(12*1.5)

Simplifying and solving for P, we get:

P = 3000 / (1 + 0.06/12)^(12*1.5)

P = $2,572.39

Therefore, the equivalent value of the money now is $2,572.39.

(b) To find the equivalent value of the money one year from now, we need to calculate the future value of $1 after one year, and then multiply it by the present value we found in part (a). The future value of $1 after one year, at 6% per year, compounded monthly, is:

FV = 1*(1 + 0.06/12)^(12*1)

FV = $1.06168

Multiplying this by the present value we found in part (a), we get:

$2,572.39 * $1.06168 = $2,735.92

Therefore, the equivalent value of the money one year from now is $2,735.92.

(c) To find the equivalent value of the money three years from now, we need to calculate the future value of $1 after three years, and then multiply it by the present value we found in part (a). The future value of $1 after three years, at 6% per year, compounded monthly, is:

FV = 1*(1 + 0.06/12)^(12*3)

FV = $1.19102

Multiplying this by the present value we found in part (a), we get:

$2,572.39 * $1.19102 = $3,066.63

Therefore, the equivalent value of the money three years from now is $3,066.63.

according to the given information we can say that the fraction of the area of the circle that is shaded is 1/4 or 0.25.

Every point in a horizontal surface that is a certain distance above another point forms a circle (centre). It is a circle made out of point that are separated from each other in a horizontal direction as a result. At all angles, it is rotating symmetric about the centre. In the closed, two-dimensional plane of a circle, each pair of points is evenly separated from the "centre." A line that pierces the circle creates a specular symmetrical line. At all angles, it rotates symmetrically about the centre.

given,

If the circle is divided into two equal parts and one of them is shaded, then the shaded area is half of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/2 or 0.5.

If the circle is divided into four equal parts and one of them is shaded, then the shaded area is one-fourth of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/4 or 0.25.

Therefore, the answer depends on how many equal parts the circle is divided into and the number of shaded parts.

Answer: To answer this question, we need to calculate the maximum possible speed of the train based on the given information and check if it is greater than 160 km/h.

First, let's use the given information to find the range of possible speeds of the train. The time taken by the train is given as 110 minutes, correct to the nearest 5 minutes. This means that the actual time taken by the train could be anywhere between 107.5 minutes and 112.5 minutes.

Converting the time to hours, we get:

Lower bound of time = 107.5 minutes = 107.5/60 hours = 1.792 hours

Upper bound of time = 112.5 minutes = 112.5/60 hours = 1.875 hours

Now, let's use the given distance of 270 km, correct to the nearest 10 km, to find the range of possible average speeds of the train. The lower bound of the distance is 265 km, and the upper bound is 275 km.

Lower bound of speed = 265 km / 1.875 hours = 141.3 km/h

Upper bound of speed = 275 km / 1.792 hours = 153.5 km/h

Therefore, based on the given information, the maximum possible speed of the train is 153.5 km/h, which is less than 160 km/h.

So, we can conclude that the average speed of the train could not have been greater than 160 km/h.

Step-by-step explanation:

When they are at the same altitude, the distance between the planes will be 3962 feet.

Because the air is less dense at high altitudes, planes can fly quicker and consume less fuel. Additionally, at altitudes of 30,000 feet or more, airplanes may steer clear of weather systems, improving the comfort level inside.

The majority of commercial airplanes are permitted to soar as high as 42,000 feet. This upper limit is frequently referred to as a "service ceiling."

The planes will be at the same altitude when t seconds have passed, in which case 25.25t + 2548 = 70.75t,

45.5t = 2548 t = 56 seconds,

and 70.75 * 56 = 3962 feet.

Answer:

A) 150%

B) 20.67 J

Step-by-step explanation:

A) To determine the efficiency of the engine, we can use the formula:

efficiency = (work output / heat input) x 100%

In this case, the engine does 62 J of work each cycle, so the work output is 62 J. We're also given that the engine absorbs 2 times as much heat as it discharges to the environment, so we can express the heat input as 2 times the heat discharged:

heat input = 2 x heat discharged

Therefore, we can rewrite the efficiency formula as:

efficiency = (62 J / (2 x heat discharged)) x 100%

Simplifying this expression, we get:

efficiency = 31 J / heat discharged

Now we need to determine the value of heat discharged. We know that the engine absorbs 2 times as much heat as it discharges, so the net heat input is 3 times the heat discharged:

net heat input = heat input - heat discharged = 2 x heat discharged - heat discharged = heat discharged

Therefore, we can express the net heat input as:

net heat input = 3 x heat discharged

Now we can use the first law of thermodynamics, which states that the net heat input is equal to the work output plus the heat discharged:

net heat input = work output + heat discharged

Substituting the given values, we get:

3 x heat discharged = 62 J + heat discharged

Solving for heat discharged, we get:

heat discharged = 20.67 J

Now we can calculate the efficiency:

efficiency = 31 J / 20.67 J = 1.50 or 150%

Therefore, the efficiency of the engine is 150%.

B) To determine the quantity of heat discharged to the environment each cycle in Joules, we can use the value we calculated above for heat discharged:

heat discharged = 20.67 J

Therefore, the quantity of heat discharged to the environment each cycle is 20.67 J.

The estimated actual temperature (x) when the temperature adjusted for wind chill (y) is -35 degrees Fahrenheit =

approximately -6.92 degrees Fahrenheit.

To estimate the actual temperature (x) when the temperature adjusted for wind chill (y) is given as -35 degrees Fahrenheit using the formula y = -26 + 1.3x, we can substitute y with -35 and solve for x.

-35 = -26 + 1.3x

Adding 26 to both sides to isolate the x term:

-35 + 26 = 1.3x

-9 = 1.3x

Dividing both sides by 1.3 to solve for x:

x = -9 / 1.3

x ≈ -6.92
