Formula for volue of cylinder is area time height. Lets find area
A=\pi r^2
diameter=2r
8=2r
r=4
Now substitute r to A= \pi r^2
A=\pi 4^2= 16\pi
Now we have formula
V=16 \pi *height=16 \pi *9=144 \pi - its the result, so B

The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.

If the radius of the base is r and the height is h, then the surface area of the cylinder is

A=2\pi r^2+2\pi rh

You're given that the area is 96\pi and the radius is 4, so you have

96\pi=2\pi\times4^2+2\pi\times4h\implies 12=4+h\implies h=8
