Question

Q. You're working for a tourism company that provides travelers with a unique "View from Above"

hot air balloon tour. If you have a round hot air balloon that is shaped like a ball and is 50 feet in

diameter, how much air does it contain? Use 3.14 for i.

Answer 1

D. 65,417 cubic feet

Explanation:

Volume of a sphere ≈ 43 × 3.14 × (radius)3

Answer 2

The balloon contain 65416.6 cubic feet.

Explanation:

Given : If you have a round hot air balloon that is shaped like a ball and is 50 feet in diameter.

To find : How much air does it contain?

Solution :

The ball is in spherical shape.

The diameter d=50 feet.

The radius is
`r=(d)/(2)`

`r=(50)/(2)=25\ feet`

The air does it contain is given by the volume of the ball.

The volume of the ball is
`V=(4)/(3)\pi r^3`

`V=(4)/(3)* 3.14* (25)^3`

`V=(4)/(3)* 3.14* 15625`

`V=65416.67\ ft^3`

Therefore, the balloon contain 65416.6 cubic feet.
