Express your answer to three significant figures and include
the appropriate units.
Explanation / Answer
It can be seen that the wheel is a solid cylinderof radius 420 with a hole at centre and a cylinder with radius 320 is cut from both sides of the solid cylinder therefore, the volume of the whole cylinder-2*(volume of cylinder cut)-volume of cyliner cut at the centre=6226636.4 mm^3 multiply this with density to get mass
