Evaluate the iterated integral by converting to polar coordinates. (give an exact answer.) )^a int_0^(sqrt(a^2-y^2)) (x^2 + y^2)^(3\/2) text( ) dx text( ) dy

The given integral is


Refer to the figure shown below.
In polar coordinates, the domain of integration is a circle with radius r = [0, a], and θ = [-π, π]. 
The element of area is 
dA = r dr dθ
x² + y² = r²

The integral may be written as
