Find the Surface Area cylinder (7.2)(9.95)

Math
h=7.2r=9.95
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=9.95 and height h=7.2 into the formula. Pi π is approximately equal to 3.14.
2(π)(9.95)2+2(π)(9.95)(7.2)
