Answer:


V=63,829.92\ cm^3

Explanation:

step 1

Find the radius of the circle

we know that

The circumference is equal to


C=2\pi r

we have


C=69.08\ cm

assume


\pi =3.14

substitute


69.08=2(3.14)r

solve for r


69.08=6.28r


r=69.08/6.28


r=11\ cm

step 2

Find the volume of the cylinder

we know that

The volume of the cylinder is equal to


V=\pi r^(2)h

we have


h=168\ cm


r=11\ cm

assume


\pi =3.14


V=(3.14)(11)^(2)(168)


V=63,829.92\ cm^3
