A well having 10 m inside diameter is dug 8.4m deep. earth is taken out of it and spread to a width of 7.5m to make embankment.
To find the height of the embankment:
First find the volume of earth(soil) taken out
which is equal to the volume of Cylinder.
Well is on the form of Cylinder, inside diameter
10 m
Radius = 5m
deep/height = 8.4 m
Volume of soil taken out=
As embankment is to be made around the well.
Outside diameter = 10+7.5+7.5= 25 m
Outside radius = 12.5 m
Since ,earth taken out does not put inside the well,so we had to put the formula like
So, the height of the embankment will be 1.6 m.
Hope it helps.
