Answer:


S.A=96\pi m^2

Explanation:

The surface area of a right circular cylinder is given by the formula;


S.A=2\pi r(r+h)

where
h=8m is the height of the cylinder and


r=4m is the radius of the cylinder.

We plug in these values into the formula to obtain;


S.A=2\pi *4(4+8)


S.A=8 *12 \pi


S.A=96\pi m^2
