A well with 10 m inside diameter is dug 8.4 m deep. Earth taken out of it is spread all around it to a width of 7.5 m to form an embankment. Find the height of the embankment.

Given,


Inside diameter of well = 10 m


Inside radius =


depth of well = 8.4 m


Volume of earth dug out =


Area of embankment formed =


Height of embankment thus formed =


40
