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

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
