2. Find the surface area of a cylindrical can of tennis balls if the height of the can is 8

alina1380 [7]

Answer:

125.7 square inches

Step-by-step explanation:

The surface area of a cylinder is the sum of the areas of the two circles on each end and the area encircling "rectangle". Note that the length of this "rectangle" is the height of the can, while the width is the perimeter of the circle. The full equation is:

$A=2 \pi r^2 +2 \pi r h\\A=2 \pi r(r+h)\\A=2 \pi (2)(2+8)\\A=40 \pi\\A=125.7$
