# Find the Surface Area cylinder (13)(3)

h=13r=3
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=3 and height h=13 into the formula. Pi π is approximately equal to 3.14.
2(π)(3)2+2(π)(3)(13)
Simplify each term.
Raise 3 to the power of 2.
2π⋅9+2(π)(3)(13)
Multiply 9 by 2.
18π+2(π)(3)(13)
Multiply 3 by 2.
18π+6π⋅13
Multiply 13 by 6.
18π+78π
18π+78π
