b.) Your friend Bob proposes that you can do this calculation more easily. He condenses the entire ice cream cone into a point mass located at the its center of mass, then uses the point mass formula (I=mr2). What would be the distance "r" that he would use, and the rotational inertia that would result from his calculation? r = X m I = X kg-m2 Is Bob's method correct? no; you need to use the object's exact shape in your "I" calculations
