Click on the picture for a helpful area and volume of a cone calculator.

The calculator will find the area along with the radius,height, or slant height of the cone when given two values.

The calculator will also calculate the volume of the cone.

Truncated Cone

A truncated cone is a solid similar to a cylinder, except that the circular bases are not equal in size. You could describe the shape like a lamp shade.

Think of it as a cone with the portion containing the vertex removed.

If the cut is parallel to the base then it is a frustum of a cone.

How to find base area

The surface area of a cone is the outside covering of the cone. Finding the surface area of a cone involves finding the lateral area and adding this to the base area of the cone.
