The surface area of a cylinder is 207.24dm2, the bottom area is 28.26dm2, and the perimeter of the bottom surface is 18.84dm. What is the volume of the cylinder in cubic decimeter?

The surface area of a cylinder is 207.24dm2, the bottom area is 28.26dm2, and the perimeter of the bottom surface is 18.84dm. What is the volume of the cylinder in cubic decimeter?

Height = side area △ bottom perimeter = (207.24-28.26 × 2) △ 18.84 = 8 (DM)
The volume of this cylinder = bottom area × height = 28.26 × 8 = 226.08 (cubic decimeter)
