A well with 20 m inside diameter is dug 10 m deep. Soil taken out of it has been evenly spread all around it to a width of 30 m to form an embankment. Find the height of the embankment.
Volume of the soil dug out = `Pi` r2h ⟹( [if gte msEquation 12]>x 40 x 40) - (
x 10 x 10 ) = 4,714 m² Height of embankment = `(Volume)/(Area)` [if gte msEquation 12]>
