find the volume of the cylinder using 3 as pi

The formula for volume is given by
It is given that the height is 3cm and radius is 9 cm and the value of pi is 3 so it follows:
[tex]\begin{gathered} V=\pi\times r^2\times h \\ V=3\times9^2\times3 \\ V=729cm^3 \end{gathered}[/tex]Hence the volume of the figure is 729 cubic centimeters.
