Therefore, TSA = Area of base + Area of the curved surface. Volume Definition. ... Total surface area of a cone formula = πrl + πr 2 = πr(r + l) Cone Volume Formula.

Calculate the volume of everyday items such as cuboids, prisms and pyramids. Use your knowledge of area to calculate the surface area of 3D shapes.

A simple guide on how to show the surface area of a cone is π × radius × length, aimed at students aged 11 to 14.
