# Find the Surface Area cylinder (8)(19) h=8r=19
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=19 and height h=8 into the formula. Pi π is approximately equal to 3.14.
2(π)(19)2+2(π)(19)(8)
Simplify each term.
Raise 19 to the power of 2.
2π⋅361+2(π)(19)(8)
Multiply 361 by 2.
722π+2(π)(19)(8)
Multiply 19 by 2.
722π+38π⋅8
Multiply 8 by 38.
722π+304π
722π+304π
Add 722π and 304π.
1026π
The result can be shown in multiple forms.
