Question

What is the surface area of a sphere with a radius of 14 units?

Answer 1

Surface area= 784π units²

Explanation:

Surface area= 4×π×r²

Surface area= 4×π×(16)²

Surface area= 4×(16)²×π

Surface area= 784π units ²

Answer 2

SA =784 pi units ^2

Explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 14

SA = 4 pi (14)^2

SA =784 pi units ^2
