Question

An agricultural field is in form of rectangle of length 20 m and width 14 m a 10 m well of diameter 7 m is dug in a corner..

Answer 1

Volume of well =volume of earth level rise in the field

pi.r^2.h=length x breadth x height

22/7 x 7/2 x 7/2 x 10=20 x 14 x height

11 x 7 x 5=20 x14 x height

height =11/8 m

hence 11/8m level rise in the field
