So the silo is composed of two parts: a cylinder and a cone. Find the volume of each, then add.

but how do you find the volume of the cone?

\(\Large V_{\text{cone}}=\frac{1}{3}Bh\) where B is the area of the base and h is the height from the apex to the base.

The base of the cone in this case is a circle with diameter 20.

\[1/3_{20}\times20\] so is that how you find the answer? to the cone?

I am not getting the right answers... could you work the problem out?

I think you meant this: \[\frac{1}{3}(10)^2(20)\pi=\frac{2000}{3}\pi\] because the radius of the circle is 10. The V of the cylinder is \(\large (10)^2\pi(80)=8000\pi\) Add them up and you get \(\Large \frac{26000}{3}\pi\) or if you need a decimal, plug this in your calculator.

The closest answer is the 27213, so I'd just take that answer.
