Question

Needing some help!!!

Answer 1

`r = 1.379 feet`

Explanation:

`r = ((3V)/(4\pi )) ^{(1)/(3) }` ------> (eq 1)

`V = 11f^(3)`

`\pi = (22)/(7)` put in (eq 1)

`r = ((3(11))/(4((22)/(7) ) )) ^{(1)/(3) }`

`r = ((33(7))/(88 )) ^{(1)/(3) }`

`r = ((231)/(88 )) ^{(1)/(3) }`

`r = (2.625) ^{(1)/(3) }`

`r = 1.379 feet`
