Question

one last question and im done for this weeks assignment..this is easy but im making an error somewhere if somebody could point it out to me id appreciate it

Answer 1

i integrated 4-x^2-y^2 and set the limits 0<x<2 and 0<y<-x+2...where am i going wrong ?

Answer 2

I would use polar/cylindrical coordinates

Answer 3

the way you integrated it the upper bound on y is wrong, you should use sqrt(4-x^2)

Answer 4

was it the circle equation that made u decide to use polar?
