R = sqrt 3 (V /( pi h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 (62.8 / (3.14 15)
R = sqrt 3 (62.6 / 47.1)
R = sqrt 3 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===

Step-by-step explanation:

\(\pi {r}^{2} \frac{h}{3} = V \\ \\ \pi {r}^{2} \frac{15}{3} = 62,8 \\ \\ \pi {r}^{2}(5) = 62,8 \\ \\ 5\pi {r}^{2} = 62,8 \\ \\ 3,99797217 ≈ \frac{62,8}{5\pi} \\ \\ 3,99797217 ≈ {r}^{2} \\ \\ 1,999492978 ≈ r \\ \\ 2 ≈ r\)
