Question

What is the surface area of the sphere below?

Answer 1

Answer:

$64\pi$

Step-by-step explanation:

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

$SA=4\pi\cdotr^{2}$

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...

$SA=4\pi\cdot4^{2}$

$SA=4\pi\cdot16$

$SA=64\pi$

Hence the surface area of the sphere is $64\pi unit square$

Answer 2

Answer:

A) 64π units

Step-by-step explanation:

SA= 4πr squared

4*π*4 squared

4 squared = 16

16*4=64

64π
