## How to Find the Surface Area of a Sphere Calculator?

The surface area of a sphere is the number of unit squares that can be fit into it and it is measured in square units. The surface area of a sphere is calculated by the following formula:

**The surface area of a sphere = 4πr ^{2},** where 'r' is the radius of the sphere.

**Solved Example:**

Find the surface area of a sphere if the radius is 4 units?

**Solution:**

The surface area of a sphere = 4πr^{2}

= 4 ×3.14 × 5^{2}

= 4 × 3.14 × 25

= 314 square units

Therefore, the surface area of the sphere = 314 square units

Similarly, you can try the calculator to find the surface area of the sphere if the radius is

1) 4units

2) 11units

3) 12units
