## How to Find the Surface Area of a Hemisphere?

A hemisphere is defined as a three-dimensional shape that is half of the sphere. When a sphere is cut by a plane passing through its center, the shape we get is called the hemisphere. A hemisphere has a curved surface and one flat circular base.

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

**The surface area of a hemisphere = 3πr ^{2},** where 'r' is the radius of the hemisphere.

**Solved Examples on Surface Area of a Hemisphere Calculator**

**Example 1:**

Find the surface area of a hemisphere with a radius measuring 5 units?

**Solution:**

The surface area of a hemisphere = 3πr^{2}

= 3 ×3.14 × 5^{2}

= 3 × 3.14 × 25

= 235.5 square units

Therefore, the surface area of a hemisphere = 235.5 square units

**Example 2:**

Find the surface area of a hemisphere with a radius measuring 7 units?

**Solution:**

The surface area of a hemisphere = 3πr^{2}

= 3 ×3.14 × 7^{2}

= 3 × 3.14 × 49

= 461.58 square units

Therefore, the surface area of a hemisphere = 461.58 square units

**Example 3:**

Find the surface area of a hemisphere with a radius measuring 12 units?

**Solution:**

The surface area of a hemisphere = 3πr^{2}

= 3 ×3.14 × 12^{2}

= 3 × 3.14 × 144

= 1356.48 square units

Therefore, the surface area of a hemisphere = 1356.48 square units

Similarly, you can try the Surface Area of a Hemisphere Calculator to find the surface area of a hemisphere if the radius is

a) 7units b)13units c) 12units
