Can y’all help me plz

Answer 1

Answer:

A. 54 pie cm³

Step-by-step 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 × $\pi$ 3³

= 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
