Question

A grain silo is shown below:

Grain silo formed by cylinder with radius 8 feet and height 172 feet and a half sphere on the top

What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi.

Answer 1

i need help. please. anyone?

Answer 2

Volume of a half a sphere is:

\[V = (2/3)\pi*r^3\]

And of a cylinder it is:

\[V = \pi*r^2*h\]

Add them up to get your needed volume.

how would i do that though? what numbers do i use?
