There are two semi circular ponds on both the sides of a rectangular play-ground.If the breath of the playground is 28 m and depth of the pond 7 m,how many litres of water can the ponds hold?Find it.

Answer 1

Given:
Breadth of rectangle = Diameter of semi circle = 28m
Radius of the semi circle =14m
Depth=7m
To prove:
Amount of water ponds can hold
Proof:
(pi) r^2xh
22/7 × 14×14×7
22×2×14×7
22×14×14
22×196 = 4312 litres

Hope it helps you!
