A cylinder and a cone are of equal height and equal bottom. The sum of their areas is 120 cubic centimeters. The volume of this cylinder is () cubic centimeters
A cylinder and a cone are of equal height and equal base. The sum of their areas is 120 cubic centimeters. The volume of this cylinder is (90) cubic centimeters
A cylinder and a cone are of equal height and equal base. The sum of their volumes is 160 cubic centimeters. The volume of a cylinder is 160 cubic centimeters______ Cubic centimeter
The volume of cylinder: 160 △ 1 + 13, = 160 △ 43, = 120 (cubic centimeter); answer: the volume of cylinder is 120 cubic centimeter
A cone and a cylinder have the same area at the bottom. The volume of the cylinder is 30 cubic centimeters larger than that of the cone. The height of the cone is 20 centimeters and the volume is 40 cubic centimeters. What is the height of the cylinder?
Base area of cone: 40 × 3 △ 20 = 6 (square centimeter); height of cylinder: (40 + 30) △ 6 ≈ 11.67 (centimeter); answer: height of cylinder is about 11.67 centimeter
