Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.

Answers

Answer 1

Answer:

V=2.8cm^3

Step-by-step explanation:

Answer 2

The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.

Calculation of the pyramid:

Since

perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.

So, here

we know that

volume of a pyramid = [tex]1/3(length * width * height)[/tex]

And,

perimeter of a square = [tex]4 * length[/tex]

6.9 = 4 x length

So,

length = 1.725

Now the volume is

[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]

= 2.8

Write the sum as a product.
sin(x)-sin(4x)

Answers

Step-by-step explanation:

Given

sin(x) - sin(4x)

= 2 cos (( x + 4x)/2) * sin ( ( x - 4x) / 2))

= 2 cos 5x/2 • sin -3x / 2

= - 2 cos 5x/2 • sin 3x/2

Hope it helps :)❤

The sum sin(x) - sin(4x) can be written as a product as 2 sin (5x/2) cos (3x/2).

What are Trigonometric Ratios?

Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.

The main three trigonometric ratios are sine, cosine and tangent functions.

We have the trigonometric formula that,

sin A - sin B = 2 sin ([tex]\frac{A+B}{2}[/tex]) cos ([tex]\frac{A-B}{2}[/tex])

Here the sum is, sin(x) - sin(4x) where A = x and B = 4x.

sin(x) - sin(4x) = 2 sin ((x+4x)/2) cos ((x-4x)/2)

                       = 2 sin (5x/2) cos (-3x/2)

We also have, cos(-x) = cos(x).

So, sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2)

Hence the product form is sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2).

The length of the 135˚ arc below is 15/4 π. Find the radius of the circle. Please explain the answer.

Answers

Answer:

The radius of the arc is 5

Step-by-step explanation:

An arc is a part of the circumference of a circle that has been cut out. It can be best understood as an incomplete circle. The length of the arc is how long the arc is.

The formula relating how long the arc is with its radius is

length of arc = [tex]\frac{\theta}{360} \times 2 \pi R[/tex]

where R is the radius we are looking for.

Θ = 135 which can be seen as the arc angle

[tex]R =\frac{l \times 360}{\theta \times 2 \pi} =\frac{(15 \pi /4) \times 360 }{135 \times 2 \pi}=5[/tex]

The radius of the arc = 5

If two angle measurements are 53° and 70,° what must the third angle measurement equal to form a triangle?

Answers

Answer:

Step-by-step explanation:

All triangles without exception, have 180 degrees.

x + 53 + 70 = 180                Add the left

x + 123 = 180                       Subtract 123 from both sides.

x + 123 - 123 = 180 - `123    Combine.

x = 57  

The sum of the measures of the three angles of the triangle is 180*

35* + 45* + z = 180*

80* + z = 180*

z = 180* + z = 180* − 80* = 100*


= 100*
