Question 81315
{{{V=(4/3)(pi)R^3-(4/3)(pi)r^3}}}
To factor something, identify the common factors to each of the 2 terms on the right side of the eqation. The common factors are {{{4/3}}} and {{{pi}}}. Next, you can apply the distributive property to "pull out" those common factors as follows:
{{{V=(4/3)(pi)(R^3-r^3)}}}
The right side is now in "factored" form, so you are done.
Good Luck,
