For cones with radius 5.4 units, the equation V = 10πh relates the height h of the cone, in units, and the volume V of the cone in cubic units. What is the volume of the cone for a height 1, 5 and 8

A cylinder has radius 4 meters. Its volume is 155 cubic meters. Find its height to the nearest tenth of a meter.

For cylinders with radius 2 units, let h represent the height of the cylinder, in units, and V represent the volume of the cylinder, in cubic units. Complete the table relating the height and volume of cylinders with radius 2 inches. Write each volume as a multiple of π, or round to the nearest cubic unit. | h | V | |---|---| | 1 | | | 2 | | | 3 | | Use the formula V = πr²h for the volume of a cylinder.
