R=9/2 cm
h=16 cm
⏭️Volume of Cylinder : π*r^2*h
Value of π= 3.1415
9^2=81
use formula volume Of cylinder
= 3.14*81/4*16
=1017.36 Cm cube

⏭️vol of sphere= 4/3 π*r^3
=4/3*π*0.3*0.3*0.3
=0.1130 cm cube
Totall Numbers of ball= vol of cylinder/ vol of 1 sphere
on dividing both we get,
=1017.36/0.1130
=9003
made from the cylinder 9003 Balls
