Thank you again for replying!
Ok, so for the area, I am getting ∏r^{2} after doing the integral.
as for dI, I put the (2/5)m in because that is what I of a sphere equals but then I realized I am looking for dI.
Thus,
dI=∫r^{2}dσ
and
I=∫(2/5)mr^{2}dI
I am still not sure of the q...
Thank you so much for the reply!
I am a little confused. I understand that I should be using a dσ. So I get something like
A=∫r^{2}sinσdσ.
then
dI=(2/5)mr^{2}dσ
This is confusing me because then the pi won't cancel out and I am missing my q. I think I need to add a dq and flip one of...
