How can you use the formula for the volume of a cylinder to remember the formulas for the volume of a cone and the volume of a sphere?

The formula for finding the volume of a cylinder is the same as the formula for a cone, except the height is divided by three, so the cylinder's formula can help you remember it.

Step-by-step explanation:

Cylinder's formula is: V= π r^2 h

Cone's formula is: V= π r^2 (h/3)

( π = pi )

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
