The radius of a basketball is 3.6 times greater than the radius of a tennis ball how many times greater is the volume of a basketball then the volume of a tennis ball

Radius of the basket ball as b & radius of the tennis ball as t

b = 3.6 t

Volume of sphere = 4/3 pi r ^3

volume of the basket ball vb = 4/3 pi b^3

volume of the tennis ball vt = 4/3 pi t^3

therefore

vb / vt = b^3 / t^3

= (3.6t) ^3 / t^3

= 3.6^3

= 46.656

so the volume of the basketball is 46.656 times greater than the volume of the tennis ball. Hope this is correct
