Homework Statement
Homework Equations
The Attempt at a Solution
As with my other recent posts, I just want to check if I'm right or wrong as I don't have an answer scheme to go by.
For this question I simply converted to polar to get:
∫∫(a+a)r drdθ
for 0<r<a, 0<θ<2π ,
which solved to give
2πa3 .
Was that correct? I'm convinced I did something wrong because it seems a very easy 7 marks.
Thanks!
