The question -
R is the region inside the circle
My attempt (converting to polar) -
Assuming we can find a quarter of the circle, than multiply by 4 for the total area...
Here I'm stuck and quite frankly it's looking a lot more complicated than I imagine it should, can someone please point out the error in my working?
On the off chance I am correct so far, can I treat those sections as radians? I don't believe I can as that wasn't the context they were used originally, so what would I do?
Thanks for your time folks.
