Answer:
[tex]r = 1.379 feet[/tex]
Step-by-step explanation:
[tex]r = (\frac{3V}{4\pi }) ^{\frac{1}{3} }[/tex] ------> (eq 1)
[tex]V = 11f^{3}[/tex]
[tex]\pi = \frac{22}{7}[/tex] put in (eq 1)
[tex]r = (\frac{3(11)}{4(\frac{22}{7} ) }) ^{\frac{1}{3} }[/tex]
[tex]r = (\frac{33(7)}{88 }) ^{\frac{1}{3} }[/tex]
[tex]r = (\frac{231}{88 }) ^{\frac{1}{3} }[/tex]
[tex]r = (2.625) ^{\frac{1}{3} }[/tex]
[tex]r = 1.379 feet[/tex]
