Answer: 57 in³
Step-by-step explanation:
1. You know that the volume (V) of gas a balloon can hold varies directly as the cube of its radius (r). Then, you can write the following expression:
Where k is the constant of proportionality.
2. You can calculate k as following:
3. Then, to calculate the cubic inches that must be released to reduce the radius down to 2 inches:
- Solve for the volume as following:
- Make the subtraction of the two volumes shown above. Then, the result is:
The scale factor is 1/3 because 9 x 1/3 = 3 and 6 x 1/3 = 2.
