Given that circle plus circle = 90, triangle times circle equals 90, square divided by triangle equals 90, then how much is square equal to? The volume of a cylinder is 6.28 cubic decimeters larger than that of a cone with the same base and height. What is the volume of a cone?

Given that circle plus circle = 90, triangle times circle equals 90, square divided by triangle equals 90, then how much is square equal to? The volume of a cylinder is 6.28 cubic decimeters larger than that of a cone with the same base and height. What is the volume of a cone?

Circle = 90 / 3 = 30
Triangle = 90 / 30 = 3
Square = 90 * 3 = 270
Cone volume = 6.28/2 = 3.14 cubic decimeter
