# Find the Surface Area cylinder (7.4)(7)

h=7.4r=7
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=7 and height h=7.4 into the formula. Pi π is approximately equal to 3.14.
2(π)(7)2+2(π)(7)(7.4)
Simplify each term.
Raise 7 to the power of 2.
2π⋅49+2(π)(7)(7.4)
Multiply 49 by 2.
98π+2(π)(7)(7.4)
Multiply 7 by 2.
98π+14π⋅7.4
Multiply 14π⋅7.4.
Multiply 7.4 by 14.
98π+103.6π
Multiply 103.6 by π.
