Someone help please thank you

See below.

Step-by-step explanation:

So we have the two functions:

And we want to find:

1)

Recall that:

is the same as:

Thus, we can substitute g(x):

And substitute that into f(x):

Distribute:

Subtract and simplify:

Thus:

2)

Similarly:

Substitute f(x):

Substitute:

Distribute:

Simplify:

Therefore:

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
