To find the surface area of a cylinder add the surface area of each end plus the surface area of the side.
Each end is a circle so the surface area of each end is , where is the radius of the end. There are two ends so their combined surface area is .
the surface area of the side is =>
The entire formula for the surface area of a cylinder is
given:
a height of
and a base diameter of =>

This unrolls into a rectangle with length2 pi*rand height 4. There are two end circles with area pi*r^2
A=2pi*r*h+2pi*r^2
=2*pi*3*4+2 pi*9
=42 pi yds ^2
