3. What is the radius of the spheres?

**Reiny**, Thursday, November 29, 2012 at 7:54pmArchimedes would have done it this way

original volume

= 50x34x18

=30600

change in volume

= 50x34x4.5

= 7650

---- caused by the two spheres

so each sphere had a volume of 3825 cm^3

V of sphere = (4/3)πr^3

(4/3)πr^3 = 3825

r^3 = 913.151..

r = cuberoot(913.151...) = appr 9.70 cm
