Answer:
spherical balls = 384
Step-by-step explanation:
V of CYLINDER = πr^2h
V of SPHERE = 4/3πr^3
v of cylinder = π×14×14×14
v of sphere = 4/3×π×3.5/2×3.5/2×3.5/2
= 1/3×π×3.5×3.5×3.5/2
NO OF SPHERICAL BALLS =
V of cylinder / v of sphere
= π×14×14×14 / 1/3×π×3.5×3.5×3.5/2
= 14×14×14×3×2 / 3.5×3.5×3.5
= 4×4×4×3×2
= 16×24
=384
