Question

What is the surface area of the sphere below?

Answer 1

A) 64π units

Explanation:

SA= 4πr squared

4*π*4 squared

4 squared = 16

16*4=64

64π

Answer 2

`64\pi`

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`
