Please help me with these questions with explanations!

1. Let f be a function of two variables defined on the planar region D shown. a) Set up (but don't compute) the double integrals for f over D in the indicated orders: i. dydx: y = Inc D T e ii. dxdy: b) Use either of your iterated integrals from Part (a) to integrate the function f(r, y) = over D. I2. An agricultural sprinkler distributes water over a circular region of radius 100 ft. To each point in the region, it supplies water to a depth (in feet) that is inversely proportional to the distance from the sprinkler (located at the circle's center). a) Find the total volume of water supplied to the region. sprinkler 100 ft b) If the sprinkler supplies water to a depth of 1/2 ft to those points 40 ft from the sprinkler, what is the total amount of water supplied to the entire region? Hint: Use your result from Part (a). Don't integrate again
