Question 339675
If the diameter is {{{d=11}}}, then the radius is {{{r=d/2=11/2=5.5}}} inches. So {{{r=5.5}}}



{{{V=(4/3)pi*r^3}}} Start with the volume of a sphere formula.



{{{V=(4/3)pi*(5.5)^3}}} Plug in {{{r=5.5}}}.



{{{V=(4/3)(3.14159265)*(5.5)^3}}} Replace {{{pi}}} with {{{3.14159265}}} (note: Use more digits of {{{pi}}} to get better accuracy).



{{{V=(4/3)(3.14159265)*(166.375)}}} Cube {{{5.5}}} to get {{{166.375}}}.



{{{V=(4/3)(522.68247714375)}}} Multiply {{{3.14159265}}} and {{{166.375}}} to get {{{522.68247714375}}} (this figure is approximate).



{{{V=696.909969525}}} Multiply {{{4/3}}} and {{{522.68247714375}}} to get {{{696.909969525}}} (again, this figure is approximate).



{{{V=696.910}}} Round to the nearest thousandth.



So the volume of the ball is approximately 696.910 cubic inches.
