Answer 1

Answer:

Step-by-step explanation:

Diameter of the well = 7 m

Radius of the well = 7/2 m

Depth of the well = 20 m

Volume of the mud dug from the well = πr²h

= 22/7 × 7/2 × 7/2 × 20

= 770 m³

Area of the rectangular plot where the mud is spread = 22 x 14

Let the height of the plotfarm be h metres.

Volume of the plot form = Volume of the mud taken from the well

22 x 14 x h = 770

h = 770 / 22x14

h = 2.5 m
