# Sphere Calculator

A sphere is defined as a three-dimensional figure that is perfectly symmetrical and round in shapes like a ball or a globe. In geometry, a sphere is a three-dimensional solid figure, which is round in shape. From a mathematical perspective, it is a combination of a set of points connected with one common point at equal distances in three dimensions.

## 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 Examples on Sphere Calculator**

**Example 1:**

Find the surface area and volume of a sphere if the radius is 3 units and verify it using the online **sphere** calculator.

**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

**Example 2:**

Find the surface area and volume of a sphere if the radius is 6 units and verify it using the online sphere calculator.

Given: Radius = 6 units

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

= 4 × 3.14 × 6^{2}

= 4 × 3.14 × 36

= 452.16 square units

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

= 4/3 ×3.14 × 6^{3}

= 4/3 × 3.14 × 216

= 904.32 cubic units

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

- Radius = 7 units
- Radius = 11 units
