Question

Compute the moment of inertia of your body as you stand tall and turn around a vertical axis passing through the top of your head and the point halfway between your ankles. Model your body as a cylinder of mass 59.5 kg and circumference 84.5 cm.

I got the answer to be 10.6 by multiplying 59.5 by .4225m^2 but it's saying my answer's too small...

Answer 1

I= 1/2 m r^2=1/2 59.5 * (.845/2PI)^2

I am not certain how you got r to be .4225, but even at that, you did not square it.
