## How to Find Surface Area and Volume of Sphere?

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 using the formula:

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

Where 'r' is the radius of the sphere.

The volume of a sphere is the capacity of the sphere or the measure of the amount of space it occupies. The volume of a Sphere can be calculated using the formula:

**The volume of a sphere = 4/3 ×π × r ^{3}**

Where 'r' is the radius of the sphere.

**Solved Example:**

Find the surface area and volume of a sphere if the radius is 3 units?

**Solution:**

Given: Radius = 3 units

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

= 4 ×3.14 × 3^{2}

= 4 × 3.14 × 9

= 113.04 square units

The volume of a sphere = 4/3 ×π × r^{3}

= 4/3 ×3.14 × 3^{3}

= 4 × 3.14 × 9

= 113.04 cubic units

Similarly, you can try the calculator to find the surface area and volume of the sphere for

- Radius = 7 units
- Radius = 11 units
