What is the surface area of the sphere below?

A) 64π units

Step-by-step explanation:

SA= 4πr squared

4*π*4 squared

4 squared = 16

16*4=64

64π

Step-by-step explanation:

Here we are given that the radius of the sphere is given as

here we are given that the radius of the sphere r=4 . Hence in order to find the Surface Area of the sphere we substitute the value of r in the formula...

Hence the surface area of the sphere is
