The Total Surface Area of the Frustum of a Cone calculator computes the total surface area of the frustum of a right circular cone, where the frustum is defined by base radius (a) and top radius (b) and height (h) in between. The surface area in this formula includes the lateral surface area (sloped sides) and the top and bottom circular areas.
