Problem 5. [Question purpose: to give practice with dierent enters of integration in 2D] Sketch the region bounded by the curves m = 0, y = 1 + (a: 1)2, and y = 1 (a: 1)? Some radioactive waste has spilled in this region, with a density f (any) grams per unit area. (a) Set up an integral to calculate the total amount spilled using d8 = dy do: (b) Set up an integral to calculate the total amount spilled using (15' 2 do: dy. [be careful that when you take square roots you choose the right sign] (c) Using f(a:, y) = my, perform whichever integral above you prefer
