# Find the numberof solid sphereeach radius 0.25cm which may be formed from a solid sphere of radius 4 cm

The radius of the sphere =  $0.25 cm$

The volume of the sphere =

$\frac{4}{3} \pi \times r^{3} \\ \frac{4}{3}\times \frac{22}{7} \times (4)^{3} \\ 267.27cm^{3}$

Radius of solid = 0.25 cm

volume of solid =

$\frac{4}{3} \times \frac{22}{7} \times (0.25)^{3} \\ = 0.6514 cm^{3}$

then the number of solid =

$\frac{267.27}{0.6514}\\ = 410.30$

Hence, the number of solid = 410
