Question

The volume of a cylinder is 176π cm³ and its height is 11 cm. What is the length of the cylinder's radius?

Answer 1

V = pi r^2 h

176 pi = pi r^2 * 11

r = 4

Answer 2

`r=4\ cm`

Explanation:

we know that

The volume of a cylinder is equal to

`V=\pi r^(2) h`

in this problem we have

`V=176\pi\ cm^(3)`

`h=11\ cm`

Substitute and solve for r

`176\pi=\pi r^(2)(11)`

simplify

`r^(2)=16`

`r=4\ cm`
