Kenji packed an exercise ball into a cylindrical package . How much space does the package occupy in terms of pi . Enter your answer in the box . The height of the package is 5 feet and the radius os 3 feet

The space that the package would occupy is 45 cubic feet.

Step-by-step explanation:

The space that the package occupies is the volume of the cylinder. The volume of an object is the 3 dimensional capacity of the object.

Volume of a cylinder = h

where: r is the radius and h is the height of the cylinder.

Given that; h = 5 feet and r = 3 feet.

The required volume = × × 5

                                   =  × 9 × 5

                                  = 45 cubic feet

The space that the package would occupy is 45 cubic feet.

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.
