Answer:
Volume = 108 cm³
Explanation:
The formula for the volume of a sphere is
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 =
× 3 × 3³
>We can rewrite 3³ as 3 × 3 × 3.
Volume =
× 3 × 3 × 3 × 3
>Now we can multiply everything.
Volume =
× 81
Volume = 108 cm³
