Hurry ! the volume of air inside a rubber ball with radius r can be found using the function v(r) = 4/3 . what does represent? the radius of the rubber ball when the volume equals 5/7 cubic feet the volume of the rubber ball when the radius equals 5/7 feet that the volume of the rubber ball is 5 cubic feet when the radius is 7 feet that the volume of the rubber ball is 7 cubic feet when the radius is 5 feet

the volume of the rubber ball when the radius equals feet

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The volume of a sphere (rubber ball) is equal to

where

r is the radius of the sphere (rubber ball)

The volume in function notation is equal to

in this problem we have

that means

The radius of the rubber ball is

and

The volume of the rubber ball is

therefore

the answer is the option B

the volume of the rubber ball when the radius equals feet

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
