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>

Step-by-step explanation:

The line where it says 2cm, extend that line to the top. You know have 2 triangles, call the one on the left A and the one on the right B

area of recntangle = bh

Rect A:

b = 5

h = 4 - 2

h = 2

bh = 5 x 2

bh = 10

Rect B:

b = 3

h = 4

bh = 4 X 3

bh = 12

Total = 10 + 12

Total = 22
