Thousand balls

We have to create a thousand balls from a sphere with a diameter of 1 m. What will be their radius?

Correct answer:

r =  5 cm

Step-by-step explanation:

D=1 m cm=1 100  cm=100 cm R=D/2=100/2=50 cm n=1000  V1=43 π R3=43 3.1416 503523598.7756 cm3 V2=V1/n=523598.7756/1000523.5988 cm3 V2=43 π r3 cm3  r=V2 34π3=523.5988 34 3.14163=5 cm   Verifying Solution:   r2=R/n1/3=50/10003=5 cm r2=r
