Find the surface area of a sphere with a radius of 7 inches?

Solution:

The surface area of a sphere is the area occupied by the curved surface of the sphere.

Circular shapes take the shape of a sphere when observed as three-dimensional structures. 

The surface area of the sphere of radius r is given by 4πr²

Where r is the radius of the sphere

π = pi = 22/7

Surface area of sphere = 4 × (22/7) × 7² = 616 inches²

Find the surface area of a sphere with a radius of 7 inches?

Summary:

The surface area of a sphere with a radius of 7 inches is 616 inches²
