PI, not pie!
v = pi r^2 h + 2/3 pi r^3
So, given the numbers above,
pi (225) h + 2/3 pi (3375) = 10800 pi
h = (10800pi - 2250 pi)/(225pi) = 38
I posted this earlier but the number was wrong. I don't know why it didn't post the other pie symbol. And ofcourse the extra pie throws me off!
A large grain silo is to be constructed in the shape of a circular cylinder with a hemisphere attached to the top (see the figure). The diameter of the silo is to be 30 feet, but the height is yet to be determined. Find the height h of the silo that will result in a capacity of 10,800(pie) ft3.
h=

Steve,
Sorry for my mistake on the PI, I was in a hurry. But I placed the answer you provided and it's wrong?
