Racquestball. The volume of rubber(in cubic centimeters) in a hollow rubber ball used in racquetball is given by V= 4/3 pie R^3- 4/3 pie 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.
V= 4/3 pie R^3- 4/3 pie r^3
V = (4/3)pi[R^3 - r^3]
-----------------------
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 cm^3
------
Comment: Will look at the graph later.
