The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.
<h3>
How to get the volume of a sphere?</h3>
The volume of air that we need is equal to the volume of the basketball.
Remember that for a sphere of radius R, the volume is:
V = (4/3)*3.14*R^3
In this case, the radius is 12cm, replacing that we get:
V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3
Then, to fully inflate the ball, we need 7,234.56 cm^3 of air.

Answer:
3.5 pounds for 14 people
Step-by-step explanation:
Given
1 pound = 4 people
Required
Determine the pounds for 14 people
Represent this with x; so, we have:
Cross Multiply
Solve for x
<em>Hence, 3.5 pounds for 14 people</em>
2r² + 3s³ - r² + 4t² - r² = 3s³ + 4t²
<span>if s = -3 and t = 5
</span>3s³ + 4t² = 3 * (-3)³ + 4 * 5² = 3 * (-27) + 4 * 25 = -81 + 100 = 19
Answer: 19
