Answer:
7.99
Step-by-step explanation:
using the formula
[tex]v = \pi \: r ^{2} h [/tex]
[tex]3014.4 = 22 \div 7 \times r ^{2} \times 15[/tex]
[tex]21100.8 = 22 \times 15 \times r {}^{2} [/tex]
[tex]21100.8 = 330 \times r {}^{2} [/tex]
[tex]21100.8 \div 330 = r {}^{2} [/tex]
[tex] \sqrt{63.94 }= r[/tex]
[tex]r = 7.99ft \: answer[/tex]
