L e be the region in r3 bounded by the three coordinate

Question

1. Evaluate the integral ∫∫_R x²y / (x² + y²) dA where R is the portion of the unit disk in the first quadrant

2. Let E be the region in R³ bounded by the three coordinate planes and the plane x+4y+2z = 4. Set up a triple integral which calculates the volume of E (you do not need to evaluate).
