Question

A circular well of diameter 6 m has been dug to a depth of 14 m. Water level was found at the
depth of 5.6 m. How much water is there in the well and how much earth has been taken out
of the well?​

Answer 1

Answer:

earth dug out was 264m^3

and water in well was 158.4 m^3.

Step-by-step explanation:

height of water it had is 14-5.6=8.4

the amount of water in the well is

2πrh

where

r=3 m

h=8.4m

so then

2*3*8.4*22/7

ie. 158.4 m^3 of water in the well

the earth dug out will be

2πrh

but here

r=3m

h=14m

so then

2*3*14*22/7

264 m^3 of earth was taken out to dug the well
