Question
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.Solution
Volume of the soil dug out = π r 2h ⟹ (22/7) x 10 x 10 x 10) = 1000 π m³. Area of embankment = Area of embankment with well - Area of well = ( x 40 x 40) - (
x 10 x 10 ) = 1500π m² Height of embankment = `(Volume)/(Area)` [if gte msEquation 12]>
