A metallic sphere of radius of 21/2 cm is melted down and then recast into small cones of radius 7/2 cm and height 3 cm each.how many of such cones can be made.
----------
The volume of the sphere:
V =
V = 1543.5 pi cc
-----------------
Vol of each cone:

v = 12.25 pi cc
------------
1543.5 pi/(12.25 pi) = 126 cones
