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:

Begin with the volume of water:

V = πr²×h = π×(9m)²×2.5m = 636.17m³

Weight of water = 636.17×10³kg

G force on water = 9.8m/s²×636.17×10³kg = 6,234.49kN

Water's center of gravity is 2.75m below edge of pool.

(2.5m/2 = 1.25m, 4m - 1.25m = 2.75m)

Work = force × distance = 6,234.49kN × 2.75m = 17,144.85

Hope i helped. <3

Step-by-step explanation:

Given, a rectangular container measuring 20 inches long by 16 inches wide by 12 inches tall is filled to its brim with water.

Let the new height of water level be x inches.

The volume of the container = (20×16×12) cubic inches

=3840 cubic inches

According to the problem,

3840 - (20×16×x) = 850

⇔3840 -320x = 850

⇔-320x =850-3840

⇔-320 x = -2990

$\Leftrightarrow x =\frac{2990}{320}$

⇔x = 9.34 inches

The new height of the water is = 9.34 inches (approx)
