Question

The cylinder shown has a diameter of 20 in. and a height of 4 in.

20 in.
Use 3.14 for T.
What is the approximate volume of the cylinder?
OA. 251.2 in.3
OB. 502.4 in.³
OC. 879.2 in.3
OD. 1,256 in.3
OE. 5,024 in.3
4 in.

Answer 1

1256 in³

Explanation:

To calculate volume of a cylinder the formula is: π · r2 · h

Since Pi is already given to us as 3.14, we now have to find the radius

The radius is always the diameter cut in half meaning it will be 20/2 which gives us 10 (radius is figured)

The height is given to us as 4 meaning the equation will be

3.14 x 10 x 10(seeing as it's radius squared) x 4

10x10 = 100

100 x 4 = 400

400 x 3.14 = 1256

The answer is in cubed(³) because it is volume

Answer 2

1256 in.3

Explanation:

V = pi x r^2 x h
V = 3.14 x 20/2 x 4
V = 3.14 x 10 x 4

V = 1256in^3
