Yanka [14]
  • Answer:

<em>4 inches</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em>Volume (cone) formula</em>

<em />V=\frac{1}{3}Ab*h\\ \\Ab=\pi*r^{2}<em />

<em />V=\frac{\pi*r^{2}*h}{3}<em />

<em />3V=\pi *r^{2}*h\\\\r^{2}=\frac{3V}{\pi*h}<em />

<em>replace</em>

<em>r² = 3×80π/15π</em>

<em>r² = 240/15</em>

<em>r² = 16</em>

<em>r = √16</em>

<em>r = 4 inches</em>

<em>Good luck !</em>
