Question 777294: Dear Math tutor,
A steel ball of volume 600cm^3 is melted down and made into three balls. A, B and C. if the volumes of A,B and C are in the ratio 7:5:3, calculate to 1 d.p the radius of each of A, B, and C.
do i add the ratios together and then divide it by 600? 600/15=13.4. then 13.4x7 ,13.4x5, 13.4x3 and use r^3=3V/4pi?
Best wishes,
Nats

The 600 is split into parts.
volume A is

volume B is

volume C is

Instead of my working and telling you the radii of those spheres, you should find them yourself.
v for volume,
