Question

when a spherical balloon is filled with air, it has a radius of 3 inches. what is the estimate for the volume of air in the balloon, in cubic inches?

Answer 1

The volume of a sphere is given by the equation $V=\frac{4}{3} \pi r^{3}$, where V is the volume and r is the radius.

To answer this question, simply plug the correct values into the equation:

$V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976$

The volume of the air in the balloon is about 113.0976 in3.

Hope this helps!!
