Question 590877: The circular faces on a net of a cylinder each have a radius of 1.75 inches. The height of the cylinder is 9 inches.
What is the surface area of the cylinder rounded to the nearest hundredth of a square inch?

The surface area is the sum of the top and bottom area plus the area of the connecting portion. The area of the faces is 2*(1.75)^2*pi and the area of the connecting portion is the height times the circumference, or 9*2*pi*1.75. The surface are is therefore about 118.20 in^2.
