Question 181953: . Racquetball. The volume of rubber (in cubic centimeters)
in a hollow rubber ball used in racquetball is given by
V=4/3 R3^3-4/3 r^3
where the inside radius is r centimeters and the outside
radius is R centimeters.
a) Rewrite the formula by factoring the right-hand side
completely.
b) The accompanying graph shows the relationship
between r and V when R =3. Use the graph to
estimate the value of r for which V = 100 cm3.

in a hollow rubber ball used in racquetball is given by
V=4/3 R3^3-4/3 r^3 pi was left out

where the inside radius is r centimeters and the outside
radius is R centimeters.
a) Rewrite the formula by factoring the right-hand side
completely.
= Factoring this far would be useful.
= There's no advantage to this.

b) The accompanying graph shows the relationship
between r and V when R =3. Use the graph to
estimate the value of r for which V = 100 cm3.
-------------------
I don't see a graph.
It says V is the volume of rubber. 100 cc seems like a lot.
The OD of a ball is 5.7 mm, so R = 2.85 cm
The total volume of the rubber and the gas inside the ball is:
V =~96.967 cc
Obviously, the composer of the problem now refers to V as the total volume, a lack on consistency.
