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

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
