If the height of a cylinder is doubled and the radius of the cylinder is halved, the volume of the cylinder
Answer(s): C
The volume of a cylinder is equal to r2h, where r is the radius of the cylinder and h is the height. The volume of a cylinder with a radius of 1 and a height of 1 is . If the height is doubled and the radius is halved, then the volume becomesThe volume of the cylinder has become half as large.
Answer(s): D
The ratio of the number of cubic units in the volume of a cube to the number of square units in the surface area of the cube is 2:3.What is the surface area of the cube?
The volume of a cube is equal to e3, where e is the length of an edge of the cube. The surface area of a cube is equal to 6e2. If the ratio of the number of cubic units in the volume to the number of square units in the surface area is 2:3, then three times the volume is equal to two times the surface area:
