area of what? circle is pie times the radius squared, rectangle is base times height, and a square is the side squared

First of all, find the area of the circle on top of the cylinder, using the formula... pi x radius^2 ... Multiply that by two because there are two circles on the cylinder. Then find the area of the rest of the cylinder, which is basically a rectangle. So, get the height, and multiply it by the circumference of the circle (also the length of one side of the rectangle) using the formula ... pi x diameter ...

Measure the rectangle, multiply the sides. Measure the hole, find the area. Subtract circle from rectangle.# 5x6 rectangle. 5*6 = 30 # Circle is 3 inches across, 3.14*(3/2)2 = 7.065 # 30-7.065 = 22.935
