Question

EMERGENCY PLS HELP: Calculate the volume.

Answer 1

Volume of a cylinder: V = π (r^2) h

Explanation:

First, find your radius and your height.

H = 21

D = 10

R = 1/2 d = 5

Then plug them into the equation: V = π (r^2) h

V = π (5^2) 21

V = π (25) 21

V = π (25 x 21)

V = π (525)

V = 525π

Answer 2

`525\pi`

Explanation:

Volume of a cylinder is given by the function
`v=\pi r^(2)h`

where v is volume, r is radius and h is height.

In order to find the radius we just divide the diameter in half and get

`(10)/(2) =5=r`

now we just plug the values in the formula

`v=\pi r^(2)h\\=\pi (5^(2))(21)\\=\pi (25)(21)\\=525\pi`
