Find the surface area of the sphere with the given dimension whose radius r = 4 units.

We will use the formula of the surface area of the sphere to find the area.

Answer: Surface area of the sphere with the given dimension whose radius r = 4 units is 64 π sq. unit.

Let see how we will find the surface area of the sphere.

Explanation:

The formula to find the surface area of the sphere is given by,

Area = 4 × π × r²

Hence, on substituting r = 4 units we will get the area.

Area = 4 × π × 4 × 4 = 64 π 

Hence, the surface area of the sphere = 64 π sq. unit.
