Question

a well of 14 M inside diameter is dug 15 M deep Earth taken out is spread all over mm of 7 m to form an embankment find the height of the embankment​

Answer 1

Vol of earth taken out= πr²h =

(22/7)*7*7*15= 2310 m³

Area of the embankment = π*(R²-r²)

Width of embankment= 7 m. So R= 7+7= 14 m

Area= (22/7)*(14²-7²)= 462 m²

Therefore, height of embankment= 2310

m³/462 m² = 5m
