The curve [tex]y = sinx\sqrt{3cosx},
0\leq x\leq \pi /2[/tex] rotates around the x-axis and creates a homogenous rotational body K.
a) Decide the volume of K.
b) Decide the center of mass for K.
(The x-coordinate of the center of mass is [tex]X_{T} = \frac{1}{m}\int_{K}^{} x dm[/tex], where m is the mass of of K.)
I have decided a) and I got the volume to be ∏ volume units. I need help with b). I would need to have the physics of the problem explained.
Please help me explain the physics, so that I from it can understand how to solve b).
