Answer:

Volume = 108 cm³

Explanation:

The formula for the volume of a sphere is
(4)/(3) π r³.

The directions say to use 3 for π.

The diagram shows that the diameter of the sphere is 12 cm, but the formula needs the radius. To find the radius, you divide the diameter by 2.

r = diameter/2 = 12cm/2 = 6 cm

>Now that we know all the parts of the formula, we can plug everything in.

Volume =
(4)/(3) × 3 × 3³

>We can rewrite 3³ as 3 × 3 × 3.

Volume =
(4)/(3) × 3 × 3 × 3 × 3

>Now we can multiply everything.

Volume =
(4)/(3) × 81

Volume = 108 cm³
