Split it: [ W = 196000 \left[ 3\int_-3^0 \sqrt9-y^2 , dy ;-; \int_-3^0 y\sqrt9-y^2 , dy \right]. ]

I’m unable to provide a direct PDF file or a specific page (like “page 54”) from Ricardo Asin’s Integral Calculus Reviewer , as that would likely violate copyright laws. However, I can offer you an original, illustrative story inspired by the kind of integral calculus problem you might find on such a page—complete with a worked-out solution in the spirit of Asin’s teaching style. Inspired by typical problems on page 54 of many integral calculus reviewers—specifically, “Applications: Work Done in Pumping Liquid.” Integral Calculus Reviewer By Ricardo Asin Pdf 54

First integral: (\int \sqrt9-y^2, dy) is a standard semicircle area formula. From (y=-3) to (0), it’s a quarter circle of radius 3. Area of quarter circle = (\frac14\pi (3^2) = \frac9\pi4). So (3 \times \frac9\pi4 = \frac27\pi4). Split it: [ W = 196000 \left[ 3\int_-3^0

Weight of the slice = volume × density of water (1000 kg/m³ × 9.8 m/s² = 9800 N/m³): [ dF = 9800 \cdot 20\sqrt9-y^2 , dy = 196000\sqrt9-y^2 , dy \quad \text(Newtons). ] Inspired by typical problems on page 54 of

[ dW = \textforce \times \textdistance = 196000\sqrt9-y^2 \cdot (3 - y) , dy. ]

Second integral: Let (u = 9-y^2), (du = -2y,dy), so (y,dy = -\frac12du). [ \int_-3^0 y\sqrt9-y^2,dy = \int_y=-3^0 \sqrtu \left(-\frac12 du\right) = -\frac12 \int_u=0^9 u^1/2 du = -\frac12 \cdot \frac23 u^3/2 \Big| 0^9 = -\frac13 (27) = -9. ] But careful with limits: actually (y=-3 \to u=0), (y=0 \to u=9), so (\int 0^9 \sqrtu (-\frac12 du) = -\frac12 \cdot \frac23 [27-0] = -9). Yes.

Numerically: (27\pi/4 \approx 21.20575), plus 9 = 30.20575. Multiply by 196000: (W \approx 5,920,327) Joules, or about (5.92) MJ.
