A rainwater system is structured as shown. The radil are the same for both rain barrels. The shorter rain barrel has a height equal to its radius. The
taller rain barrel has a height twice its radius. The total surface areafor both barrels with no top is about 40,212 square centimeters.
How is the surface area calculated and what is the radius?
Each rain barrel is modeled by a
The radius of the rain barrels is approximately
centimeters
