What is the surface of a sphere with a radius of 13 units?

The correct answer is option B.   676π units²

Step-by-step explanation:

Formula:-

The surface area of a sphere = 4πr²

Where r is the radius of sphere

To find the surface area of given sphere

Here r = 13 units

Surface area = 4πr²

 = 4 * π * 13²

 = 4 * π * 169 = 676π units²

Therefore the  correct answer is option A.   676 units²

the answer is a.
