∬R​10(x+y)dA where R is the region that lies to the left of the y-axis between the circles x2+y2=1 and x2+y2=9. When transforming an integral ∬R​f(x,y)dA to polar coordinates, we must substitute for x and y in f(x,y), substitute for dA, and find polar limits for the double integral. First of all, in polar coordinates, x+y becomes and dA=
