# Find the Surface Area cylinder (7.3)(4.5)

h=7.3r=4.5
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=4.5 and height h=7.3 into the formula. Pi π is approximately equal to 3.14.
