Radius of the solid sphere, R = 4 cm
Radius of each solid hemisphere, r = 2 cm
It is given that, the solid sphere of radius 4 cm is melted and recast into n solid hemispheres of radius 2 cm each.
∴ n × Volume of each solid hemisphere = Volume of the sphere
(R = 4 cm and r = 2 cm)
Thus, the value of n is 16.
If a solid sphere of radius 4 cm is melted and recast into n solid hemispheres of radius 2 cm each, then n = ___16___.
