The given sphere has a radius of r = 4 cm.

It is required to find the volume of the sphere using 3 for π.

The given volume formula is:

$V=(4)/(3)\pi r^3$

Substitute r=4 and π=3 into the volume formula provided:

$V\approx(4)/(3)*3*4^3=\frac{4}{\cancel{3}}*\cancel{3}*4^3=4*64$

Evaluate the product to get:

$V\approx256\operatorname{cm}^3$

The required volume is approximately 256 cm³.
