Question

# A solid sphere of radius 3 cm is melted and then cast into smaller spherical balls, each of diameter 0.6 cm. Find the number of small balls thus obtained.

Solution

## Let number of small balls = x ∴ Volume of x small balls = Volume of sphere 43π(0.3)3x=43π(3)3x=43×π×3×3×343×π×310×310×310x=1000
