Answer:The total surface area of a cone is the sum of the area of its base and the lateral (side) surface. 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.
