With a rim thickness of 2 cm, and an average radius of 5 cm,
the radius of the outside of flywheel must be 5cm + 2cm/2= 6cm,
and the inner edge of the rim must be 5cm - 2cm/2= 4cm from the axle.
The rim is a 2-cm tall 6-cm diameter cylinder with a 4-cm circulat hole in the middle.
The volume of the 2-cm tall 6-cm diameter cylinder is

.
The volume of the 4-cm hole is

.
The volume of the rim is the difference. In cubic centimeters, it is

Using , the volume of the rim of the flywheel is

.
