Frustum volume

Frustum of a cone:
Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.

e.g. Flower pots have a shape as the frustum of a cone.

The surface area and the volume of the frustum of a cone can be calculated using standard formulae.

CSA of the frustum of a cone = πl( r₁ + r₂).

where r₁ = radius of the larger circular face of the frustum, r₂ = radius of the smaller circular face of the frustum, and l = slant height of the frustum.

l = h2+(r1-r2)2h2+(r1-r2)2 and h is the height of the frustum.

TSA of a frustum of a cone = πl(r₁ + r₂) + πr₁² + πr₂²

Volume of the frustum of a cone = (1/3) πh (r₁² + r₂² + r₁ r₂)
