Question

Which expression can be used to find the volume of the cylinder in this composite figure?

Answer 1

Answer:

The volume of the cylinder is $112\pi\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

$V=Bh$

where

B is the area of the base

h is the height of the prism

$B=\pi r^{2}$

In this problem we have

$r=4\ cm$

$h=7\ cm$

substitute

Find the area of the base B

$B=\pi (4^{2})$

$B=16\pi\ cm^{2}$

substitute in the formula of the volume

$V=16\pi (7)$

$V=112\pi\ cm^{3}$
