Question

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

A. 449 units2
B. 784 units2
C. 784 units2
D. 288 units2

Answer 1

784pi units ^2

Explanation:

Answer 2

`SA=784\pi\ units^(2)`

Explanation:

we know that

The surface area of a sphere is equal to

`SA=4\pi r^(2)`

we have

`r=14\ units`

substitute

`SA=4\pi (14)^(2)`

`SA=784\pi\ units^(2)`
