## 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 Examples on Surface Area of a Sphere Calculator**

**Example 1:**

Find the surface area of a sphere if the radius is 5 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

**Example 2:**

Find the surface area of a sphere if the radius is 7 units?

**Solution:**

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

= 4 × 3.14 × 7^{2}

= 4 × 3.14 × 49

= 615.44 square units

Therefore, the surface area of the sphere = 615.44 square units

**Example 3:**

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 × 4^{2}

= 4 × 3.14 × 16

= 200.96 square units

Therefore, the surface area of the sphere = 200.96 square units

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

1) 4units, 2) 11units, 3) 12units
