find the volume of the sphere using 3 as pi

It is given that the radius of the sphere is 7 cm.
the value of pi is 3
The formula for volume is given by:
[tex]\begin{gathered} V=\frac{4}{3}\times\pi\times r^3 \\ V=\frac{4}{3}\times3\times7^3 \\ V=1372cm^3 \end{gathered}[/tex]Hence the volume is 1372 cubic centimeters.
