Answer:

A. 54 pie cm³

Explanation:

height of the cylinder = 6 × radius of one sphere.

= 6 × 3

= 18 cm

as we can see 3 spheres make up the height of one cylinder,

height of one sphere = 6 cm (3 + 3)

with three spheres it becomes = 6 × 3

= 18 cm

  • volume of a cylinder =
    \pi r² h

=
\pi × (9)² × 18

= 27 × 6
\pi

  • volume of a sphere = 4/ 3 ×
    \pi

= 36
\pi

  • for 3 spheres

volume = 3 × (36
\pi )

= 27 × 4
\pi

volume of the empty space

= volume of cylinder- volume of 3 spheres

= 27 × 6
\pi - 27 × 4
\pi

= 27
\pi ( 6 - 4)

= 27 × 2
\pi

= 54
\pi cm³
