Question

How many spheres of radius 1mm can be made from a solid sphere of diameter 0.5m ?

Answer 1

Answer:

Step-by-step explanation:

r=1mm

R=0.5/2m=250mm

Volume of bigger sphere=no. of spheres ×volume of smaller sphere

4/3πR³=4/3πr³×X                            [ X is taken as number of spheres]

4/3×3/4×π/π×R³=r³×X

250×250×250/1×1×1=X

∴X=15625000 SPHERES
