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

Answers (1)

The radius of the sphere =  $$ 0.25 cm $$

The volume of the sphere =

                                            $$ frac43 pi 	imes r^3 $$\$$ $$ frac43	imes frac227 	imes (4)^3 $$\$$ $$ 267.27cm^3 $$

Radius of solid = 0.25 cm 

volume of solid =

                    $$ frac43 	imes frac227 	imes (0.25)^3 $$\$$ $$ = 0.6514 cm^3$$

then the number of solid = 

                                           $$ frac267.270.6514$$\$$ $$ = 410.30 $$

Hence, the number of solid = 410
