Best Answer

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A. = πrl, where l is the slant height of the cone.

pi * r * (r + sqrt(r^2 + h^2))

Surface area of a sphere = 4πr2

The formula for the area of a cone is one-third multiplied by the base multiplied by the hight.

How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.

No, the formula is far from simple - requiring elliptical integrals.
