Answer:
Hiiiiiiii ! :) so here's a step by step explanation okay, starting with the first step below. Hope it helps you ! :) :)
Step-by-step explanation:
<u>Begin with the volume of water: </u>
V = πr²×h = π×(9m)²×2.5m = <u>636.17m³</u>
<u>Weight of water = 636.17×10³kg </u>
<u>G force on water = 9.8m/s²×636.17×10³kg = 6,234.49kN </u>
<u>Water's center of gravity is 2.75m below edge of pool. </u>
(2.5m/2 = 1.25m, 4m - 1.25m = 2.75m)
Work = force × distance = <u>6,234.49kN × 2.75m = 17,144.85</u>
