# Find the Surface Area cylinder (7yd)(2yd) h=7ydr=2yd
The surface area of a cylinder is equal to the sum of the areas of the bases each having an area of π⋅r2, plus the area of the side. The area of the side is equal to the area of a rectangle with length 2πr (the circumference of the base) times the height.
Substitute the values of the radius r=2 and height h=7 into the formula. Pi π is approximately equal to 3.14.
