Surface area is total area covered by the entire surface of the 3-dimensional object. A cone is made of a circle the base and a cone. To find the surface area we need to add the area of circle and lateral surface area. Surface area of a cone calculator is used to find the area of cone with the given radius and height

Example 1: Calculation of the surface area of the cone:

For a given question we need to know the radius and the lateral height of the cone.

If the radius is donated by R and the lateral height is donated by H.

Area of circle = π R2

Lateral surface area = 2πH

Surface area of the cone = πR2 + 2πH

Example 2: Find the surface area of cone if height of the cone is given?

For a given question we know the radius R of the cone. And the height h is given.

We will find the lateral height of the cone by Pythagorean Theorem
