You were given the formula you need along with the radius of 4. Filling in that formula with the info provided and we have [tex]V= \frac{4}{3} (3.14)(4^3)[/tex]. Simplifying, we have [tex]V= \frac{4}{3}(3.14)(64) [/tex]. Doing the math on that gives us a volume of 267.9 inches cubed, third choice down.
