Surface Area of a Cone

The equation for finding the surface area of a right circular cone:

Lateral Surface Area = (π * R) * [sqrt(R² + H²)]
Base Surface Area = π * R²
Total Surface Area = Lateral SA + Base SA

• π = Pi ~ 3.14159
• R = Radius
• H = Height

Currently when solving for the radius or height the slant height must be entered, not the total surface area.
