Question

a well with 14m inside diameter is dug 50 deep Earth taken out of it is spread all around a rectangular field of length 110 metre and with 100 metre find the increase in the height of field​

Answer 1

Answer:

Step-by-step explanation:

volume of earth taken out = πr²h

      = 22/7 × 14 × 14 × 50

      = 22 × 2 × 14 × 50

      = 30800

30800 = l × b × h of rectangular field

30800 = 110 × 100 × h

h = 30800 / 110 × 100

  = 308 / 11

  = 28 m
