If the side area of a cylinder is 942 square centimeters and the volume is 2355 cubic centimeters, its bottom area is () flat If the side area of a cylinder is 942 square centimeters and the volume is 2355 cubic centimeters, its bottom area is () square centimeters
The side area is the perimeter of the bottom multiplied by the height 2 π R * H = 942
Volume is base area times height π R ^ 2H = 2355
Comparing the two formulas, r = 5cm
The bottom area is π R ^ 2 = 25 π = 25x3.14 = 78.5 square centimeter
