Anyone help me with volumes matter please....?
How to find the volume of a solid S of a right circular cone with height h and base radius r?

Question

What I try is.. as it was found that
$$r = \sqrt{c ^{2}-h ^{2}}$$
so the cross sectional area is A(h)= pi r^2 = pi (c^2-h^2)
 from the drawing.. 
a=0, b=h so the volume is
$$\int\limits_{0}^{h}A(h) dh = \int\limits_{0}^{h} pi*(c ^{2}-h ^{2}) dh = 1/3 pi * r ^{2} h$$

but this wasn't quite right.
