**Formula of the Surface area of a Sphere**

Surface Area = 4πr² Where

π = pi which is approximately equal to 3.141

r = Radius of the sphere

**How to calculate the Surface area of a Sphere?**

- Take the square of the radius
- Multiply the answer with 4 π

let’s assume the Radius of the sphere is 8 cm then

= 4πr²

= 4 x 3.141 x 8^{2}

= 804.24772 cm²
