## 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 **√** (h^{2} + r^{2})and the area of the circular base is equal to π r^{2}

Surface area of the cone = π r(r +(√ (h^{2} + r^{2})

## 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 +(√ (h^{2} + r^{2})

π × 20 (20 + √(10^{2} + 20^{2}))

= 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 +(√ (h^{2} + r^{2})

π × 7 (7 + √(5^{2} + 7^{2}))

= 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 +(√ (h^{2} + r^{2})

π × 12 (12 + √(6^{2} + 12^{2}))

= 957.69 square units

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

Similarly, you can try the surface area of right cone calculator to find the surface area of the right cone

- h = 20, r = 20
