They give the formula as: Surface Area = (2 • π • r²) + (2 • π • r • height) However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder. Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the (2 • π • r • height) part of the formula. So, r = 3 inches and height = 8 * 3 inches, the side area equals 2 * PI * r * height 2 * 3.14159 * 3 * 24 =
