A cylindrical well is 25 meters deep and has a diameter of 1.8 meters. Approximately how many cubic meters of soil were dug out to make the well? (Use π = 3.14.)

Respuesta :

Height=25m
diameter=1.8m
so radius=0.9m
soil dugged out to.make well=vol.of well
=pi×r^2×h
=3.14×0.9×0.9×25
=3.14×25×0.81
=63.585m^3

The amount of soil dug out of well is 63.585 [tex]m^{3}[/tex].

How to calculate the volume of cylinder?

Volume of Cylinder= [tex]\pi r^{2}h\\[/tex]

Given values: [tex]\pi[/tex]=3.14

                      r=0.9 m (d/2)

                      h=25 m

Volume:

[tex]3.14(0.9^{2} )25[/tex]

=63.585 [tex]m^{3}[/tex]

Therefore 63.585 cubic meters of soil was dug out.
