How to Calculate Area of a Sphere using the radius?

## Surface Area of a Sphere Calculation

Sphere is the three dimensional object of a circle. The area of the sphere is the measurement of the size of the surface. It is a perfect round geometrical three dimensional figure which is of a ball form.

The area / surface area is the outer surface of the sphere with diameter d.Let us learn here how to calculate the area of a sphere.

**Formula:**

**Surface Area of a Sphere A = 4 x π x radius**^{2}

Where,

π (Pi) is a constant which is equal to 3.14

**Step 1:**Let us consider an example to find the area of a sphere whose radius is 5 cm.

Given,

Radius = 5 cm

Applying the values in the formula,

A = 4 x π x radius^{2}A = 4 x 3.14 x 5^{2}A = 4 x 3.14 x 25

A = 314 cm^{2}

**Result:**

Area of Sphere

**A = 314 cm**^{2}
