For a conical frustum:

Lateral Surface Area = π(r1 + r2)s = π(r1 + r2)√((r1 - r2)2 + h2)Top Surface Area = πr12Base Surface Area = πr22Total Surface Area = π(r12 + r22 + (r1 * r2) * s) = π[ r12 + r22 + (r1 * r2) * √((r1 - r2)2 + h2) ]
The frustum of a cone looks like a plant pot and its curved surface area is: pi*(r1+r2)*l whereas r1 is the top radius and r2 is the bottom radius with l being its slanted length.
The formula for the surface area of a sphere is: 4 pi r 2
It depends on the formula that describes the surface itself. "Curved surface area" is not enough information to answer the question.
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
