Calculate radius (1 Viewer)

[nsbrando]

A set of 12 identical metal ballbearings was made from 10cm^3 of metal, Calculate the radius of each ballbearing

How do i do this Question???

 

[Carrotsticks]

10cm^3 made 12 ball bearings, so therefore each ball bearing has volume 10/12 = 5/6 cm^3.

But remember the formula for the volume of a sphere: V = 4/3 pi r^3 = 5/6.

Now solve for r.

i think i might have a wrong answer for the radius
