Find (h•g)(x) h(x)= 3x-3 and g(x)=x^2+3

Answers:
A: 3x^3 - 3x^2 + 9x

B: 3x^3 - 3x^2 + 9x - 9

C: 3x^3 + 3x^2 + 9x - 9

D: 3x^3 - 9

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!
