(a) What is the moment of inertia (kg/m2

) of a solid cylinder rotating about an axis parallel to the symmetry axis but passing through the edge of the cylinder?

(b) What is the moment of inertia (kg/m2

) of a solid sphere rotating about an axis tangent to its surface?

The wording in (a) is confusing me. I tried but wasn't even close on both.

a)=0.0674

b)=0.0629

here are the answers can someone help me figure out how?
