Find the surface area of the cylinder in terms of pi.

Height = 8 in

Diameter = 4in

1) the area of the "side" of the cylinder is A1 = pi (4 in).

2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in) ^2 (since the radius of the cyl. is 2 in).

The desired total surface area is A = A1 + A2. Keep "pi; " do not substitute a numerical value for "pi."
