Use cylindrical coordinates to calculate :
∫∫∫Wx2+y2dVW:x^2+y^2≤25,0≤z≤2
∫∫∫W(x^2+y^2)dV=
Answer:
To solve this problem using cylindrical coordinates, we need to express the integrand and the limits of integration in terms of cylindrical coordinates. In cylindrical coordinates, a point in 3D space is represented by the radius (r), the angle (theta), and the height (z), where:
x = r cos(theta)
y = r sin(theta)
z = z
The volume element in cylindrical coordinates is given by:
dV = r dr dtheta dz
Now we can write the integral as:
∫∫∫W(x^2+y^2)dV = ∫∫∫W(r^2) r dr dtheta dz
The limits of integration are given by:
0 ≤ z ≤ 2 (since the region of integration is between z=0 and z=2)
0 ≤ r ≤ 5 (since the region of integration is within the circle of radius 5 in the xy-plane)
0 ≤ theta ≤ 2π (since the region of integration extends throughout the entire circle in the xy-plane)
Therefore, we can write the integral as:
∫∫∫W(r^2) r dr dtheta dz
= ∫0^2 ∫0^5 ∫0^2 (r^2) r dz dr dtheta
Integrating with respect to z first, we get:
∫0^2 ∫0^5 ∫0^2 (r^2) r dz dr dtheta
= ∫0^2 ∫0^5 [(r^2) r (2-0)] dr dtheta
= 2 ∫0^5 (r^3) dr ∫0^2 dtheta
= 2 (1/4) (5^4) (2)
= 1250
Therefore, the value of the integral is 1250.

The lateral area of a cone is 587 pi symbol cm^2. The radius is 32cm. Finf the slant height to the nearest tenth.
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.

What length of rope (radius) will he need to accomplish this activity?
Round your answer to the nearest foot, and please show your work.
The length of rope Jungle John will he need to accomplish this activity is 30 feet.
How do we calculate?
the formula for arc length is
L = rθ
where L = length of the arc,
r =e radius of the circle,
θ = central angle of the arc in radians.
θ = (115∘/180∘)π = 2.0089 radians
60 feet = r(2.0089 radians)
r = 60 feet / 2.0089 radians
r = 29.85 feet
r is approximated to 30 feet

A train travelled along a track in 110 minutes, correct to the nearest 5 minutes.
Jake finds out that the track is 270 km long.
He assumes that the track has been measured correct to the nearest 10 km.
Could the average speed of the train have been greater than 160 km/h?
You must show how you get your answer.
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.

What will their altitude be when they're at the same altitude?
When they are at the same altitude, the distance between the planes will be 3962 feet.
Why do aircraft go at 30000 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.
What's the maximum altitude an aircraft can travel?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,

chill (in degrees Fahrenheit, given a 30 mph wind) is given by
the following formula:
y = -26 +1.3x
Estimate the actual temperature if the temperature adjusted
for wind chill is -35 degrees Fahrenheit.
The estimated actual temperature (x) when the temperature adjusted for wind chill (y) is -35 degrees Fahrenheit =
approximately -6.92 degrees Fahrenheit.
How do we estimate the actual temperature?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
Thus, the estimated actual temperature (x) when the temperature adjusted for wind chill (y) is -35 degrees Fahrenheit would be approximately -6.92 degrees Fahrenheit.

anyone know what the area of triangle ABC is?
The area of triangle ABC is 6cm²
What is a triangle?A triangle is a three-sided polygon that consists of three edges and three vertices. It is also known as the trigon and has special names such as the hypotenuse (opposite the right angle) and legs (the other two sides). It can also refer to a percussion instrument consisting of a rod of steel bent into the form of a triangle open at one angle.
The area of the triangle is given as
Area= 1/2absinC
But the CosB = Adj/Hypo
Cos60 = Adj/12
1/2 = Adj/12
corss and multiply to have
2A = 12
Therefore Adj = 6
Therefore base = 6*2 = 12
Applying the formula we have Area= 1/2acsinB
Area = 1/2* 12*12*Cos60
Area = 12*1/2 =6cm²

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.
What is circle?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.

Find the circumference
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)
