I need help solving the 5 questions shown in the screenshot. Please be organized. Thank you in advance!

1. Evaluate dx dy. /6y-y2 /32 + y2 9-22 9-x2-12 2. Evaluate (x2 + y2 + 22)2 dz dy dx. 2=0 2V/4-12 3. Evaluate VAr2 + 12 dy dx. =0 Jy=0 4. Evaluate (2y2 + x)ey-"dA, where R is the first quadrant region bounded by the JR curves my = 1, xy = 3, x = y and x = y2 +4. 5. Determine the area bounded by the curves y = va, y = 4vr, x = 9vy and x = 25vy
