Answer: v[5/7] represents the volume of air inside a rubber ball with radius 5/7 units, such that
Step-by-step explanation:
Given: The volume of air inside a rubber ball with radius r can be found using the function.
Here volume is a dependent variable on radius (independent variable).
Therefore, the value of v[5/7] represents the volume of air inside a rubber ball with radius 5/7 units.

Answer:
we know that
The volume of a sphere (rubber ball) is equal to
V = 4/3pi r^3
where r is the radius of the sphere (rubber ball)
The volume in function notation is equal to
V(r) = pi r^3
in this problem we have
V(5/7)
that means
The radius of the rubber ball is 5/7 ft and the volume of the rubber ball is V(5/7) ft^3
<u>therefore, the answer is the option B</u>
the volume of the rubber ball when the radius equals 5/7 feet
