How to Find the Surface Area of Right Cone?

A right-angled cone is defined as a three-dimensional solid triangle rotated about one of its perpendicular sides such that it forms a circular disc at the base, it can also be viewed as a stack of non-congruent discs such that the ratio of the radius of adjacent discs remains a constant. The surface area of a cone is given by the sum of the area of all the curved surface and circular base

The area of the curved surface is equal to π r l(where l is equal to √ (h² + r²)and the area of the circular base is equal to π r²

Surface area of the cone = π r(r +(√ (h² + r²)

Solved Examples on Surface Area of Right Cone Calculator

Example 1:

Find the surface area of right cone with height h = 10 units and r = 20 units

Solution:

We have, h = 10 and r = 20

Surface area of the right cone = π r(r +(√ (h² + r²)

π × 20 (20 + √(10² + 20²))

= 2660.25 square units

The surface area of the right cone is 2660.25 square units.

Example 2:

Find the surface area of right cone with height h = 5 units and r = 7 units

Solution:

We have, h = 5 and r = 7

Surface area of the right cone = π r(r +(√ (h² + r²)

π × 7 (7 + √(5² + 7²))

= 342.94 square units

The surface area of the right cone is 342.94 square units.

Example 3:

Find the surface area of right cone with height h = 6 units and r = 12 units

Solution:

We have, h = 6 and r = 12

Surface area of the right cone = π r(r +(√ (h² + r²)

π × 12 (12 + √(6² + 12²))

= 957.69 square units

The surface area of the right cone is 957.69 square units.
