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

Answer:

$r=4\ cm$

Step-by-step 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

$r^{2}=16$

$r=4\ cm$
