Find the Surface Area cylinder (8)(3)

Math
h=8r=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.
2π⋅(radius)2+2π⋅(radius)⋅(height)
Substitute the values of the radius r=3 and height h=8 into the formula. Pi π is approximately equal to 3.14.
2(π)(3)2+2(π)(3)(8)
