An irregular shaped object of mass 2.45 kg has a moment of inertia 5.782 kgm2 about an axis through a point 1.40 m from its center of mass. Calculate the moment of inertia about a parallel axis through its center of mass.(adsbygoogle = window.adsbygoogle || []).push({});

I used the parallel axis theorem,

I= I_c + Mh^2

I= 5.782 +(2.45)(1.40)^2

I= 10.6 kgm^2

This wasn't right.. can someone tell me what I'm doing wrong. Thanks
