A company makes plastic beach balls with a radius of 8 inches. How many cubed inches of air does a person need to fill 10 beach balls for a birthday party? Use 3.14 for π and round to the nearest hundredth.

Answer:

Rounding to the nearest hundredth, we can say that approximately 10,752.9 cubic inches of air are needed to fill 10 beach balls for the birthday party.

Explanation:

We can use the formula for the volume of a sphere, which is V = (4/3)πr³, where V represents the volume and r represents the radius.

Given that the radius of each beach ball is 8 inches, we can substitute this value into the formula:

V = (4/3)π(8 inches)³

Now let's calculate the volume:

V = (4/3) * 3.14 * (8 inches)³

V ≈ 1075.29 cubic inches

(This gives us the volume of a single beach ball.)

To find the total volume of air needed to fill 10 beach balls, we multiply the volume of one beach ball by 10:

Total volume = 1075.29 cubic inches * 10

Total volume ≈ 10752.9 cubic inches

=10,752.9 cubic inches
