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...
