Question

A field is in the form of a rectangle of length 20m and width is 14 m and 10 m deep well is dug

Answer 1

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

$\pi \: r ^{2} h = lbh$

22/7×7/2××7/2×10=20×14×h

11 ×7×5=20×14×h

h. =11/8m

Therefore, the

level rise in the field is 11/ 8 metre.

I hope this will help you.

Thank you
