We can dig out the soil from the well equal to volume of well.
Height(h) of well is = 15 meters.
Diameter = 1.6 meters.
So radius(r) = [tex] \frac{1.6}{2} = 0.8 [/tex] meter.
As well in cylindrical shapes.
So volume of well = [tex]\pi r^2h[/tex]
= [tex]\pi * (0.8)^2 * 15[/tex]
[tex]= 9.6 * \pi[/tex]
In general [tex]\pi = 3.14[/tex]
So volume of well is = [tex]9.6 * 3.14[/tex]
[tex]= 30.144[/tex] cubic meter.
So we can dig out 30.144 cubic meter soil from well.
