This is a very long problem so I drew it to make things simpler.

Part a) tells me to set up a double integral in polar coordinates giving the total population of the city.

I have the following:

2π.....4

∫......∫ δ(r, θ) r dr dθ. Is this correct?

π/2...1

For part b) I was plugging in numbers, but I feel it can be both i) and ii). Can someone help me figure this out?

For part c) all I would need to do is use what I find in part b) as the integrand for the double integral in part a).

Thank you!
