hii!!!
here's ur answer...
we know that the tennis ball is in the shape of sphere.
ok let me give u an example for finding the diameter.
let the volume of the ball be=21cm³
4/3πr³=113.04cm³
4/3×3.14×r³=113.04cm³
12.56/3×r³=113.04cm³
r³=113.04/1×3/12.56
r³=9×3
r³=27
r=³√27
r=3cm
as we know that the diameter is double of radius therefore diameter is =3×2
=6cm
hope this helps....
