Calculate the moment of inertia (in kg.m ) of a skater given the following information. (a) The 88.0 kg skater is approximated as a cylinder that has a 0.150 m radius. 1.0 kg.m2 (b) The skater with arms extended is approximately s cylinder that is 82.0 kg, has a 0.150 m radius, and has two 0.750 m long arms which are 3.00 kg each and extend straight out from the cylinder like rods rotated about their ends. 1.203 x kg.m2
