Question 29862
I will solve, but the volume of a cone is (1/3)(pi)(r^2)(h)
To solve for the height, you must get "h" by itself....
V=(1/3)(pi)(r^2)(h)
(V)/((1/3)(pi)(r^2))=h
Know, we plug in the numbers..... (diameter is 12, radius is 6, so r^2 is 36)
100/((1/3)(3.14)(36)=h
about 2.7 feet is your height!

the answer is (if you want to check for yourself) is....

2.6539278131 and more
