The area of a 2D form is the amount of space within its perimeter. The surface area of the sphere in term of π is 64π ft².
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that the diameter of the sphere is 4 ft. Therefore, the surface area of the sphere is,
Surface area of sphere = 4πr²
= 4 × π × (4ft)²
= 64π ft²
Hence, the surface area of the sphere in term of π is 64π ft².
