Question

The diameter of this beach ball is 12 inches.

Answer 1

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is $\frac{4}{3}$ × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = $\frac{4}{3}$ × π × r³

→ Let's substitute in the values

Volume = $\frac{4}{3}$ × π × 6³

→ Simplify

Volume = $\frac{4}{3}$ × π × 216

→ Simplify further

Volume = 288π or 904.78
