A 45 figure skater is spinning on the toes of her skates at 1. Her arms are outstretched as far as they will go.

A 45 figure skater is spinning on the toes of her skates at 1.0 . Her arms are outstretched as far as they will go. In this orientation, the skater can be modeled as a cylindrical torso (40 , 20 average diameter, 160 tall) plus two rod-like arms (2.5 each, 66 long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to be a 45 , 20--diameter, 200--tall cylinder.
