Answer:


\large\boxed{\pi(2ft)^2(8.5ft)+(1)/(3)\pi(2ft)^2(13ft-8.5ft)}

Explanation:

The formula of a volume of a cylinder:


V=\pi r^2H

The formula of a volume of a cone:


V=(1)/(3)\pi r^2H

r - radius, H - height

We have in

cylinder:

r = 4ft : 2 = 2ft, H = 8.5ft

cone:

r = 4ft : 2 = 2ft, H = 13 ft - 8.5ft

The volume of the silo:


V=V_(cylinder)+V_(cone)

Substitute:


V=\pi(2ft)^2(8.5ft)+(1)/(3)\pi(2ft)^2(13ft-8.5ft)
