The volume of a cone with equal base and height is 6.8 cubic decimeters less than that of a cylinder. The volume of a cone is () cubic decimeters. What is the volume of a cylinder? Why Explain why it's like this. Come on
3.4; 10.2; because the cone volume formula is one-third times the bottom area times the height, and the cylinder volume formula is one-third times the bottom area times the height, the difference is two-thirds times the bottom area times the height
The volume of a cylinder is 20 cubic decimeters more than that of a cone. What is the volume of the cylinder?
The volume of a cone is 20 (3-1) = 10 (cubic decimeter); the volume of a cylinder is 10 × 3 = 30 (cubic decimeter); a: the volume of this cylinder is 30 cubic decimeter
A cylinder and a cone are of equal height and equal bottom. The sum of their volumes is 120 cubic meters. The volume of a cylinder is 120 cubic meters______ Cubic meters. What's the volume of a cone______ The volume ratio of a cone to a cylinder is (______ ：______） ．
The volume ratio of a cone with equal base to a cylinder is 1:3, 3 + 1 = 4 (parts); 120 × 34 = 90 (cubic meters); 120 × 14 = 30 (cubic meters); answer: the volume of a cylinder is 90 cubic meters, the volume of a cone is 30 cubic meters. The volume ratio of a cone to a cylinder is 1:3
