Answer 1

Answer:

1.4m

Step-by-step explanation:

Given r = 4.2 m, h = 38 m

Volume of well

= pi*r*r*h

= 22/7*4.2*4.2*38

= 22*.6*4.2*38

= 21067. 2 m^3

Let rise in level of field = d

Then,

Volume of Reactangular field

= Volume of well

l*b*d = 21067.2

130*115*d = 21067.2

d = 21067.2/(130*115)

d = 162/115

d = 1.4 m

Rise in level of field = 1.4 m
