Here is the formula x-(x*.09)=90 the answer 98.9
The quotient is 13/9 or 1 4/9 or 1.4
We need 30 glass spheres whose TOTAL volume = 3,392.92 cubic inches.
Therefore each of the 30 spheres must have a volume of 3,392.92 / 30 =

cubic inches
Sphere Volume = <span> 4/3 • <span>π <span>• r³
radius^3 = </span></span></span>Sphere Volume / <span>(4/3 • <span>π)
