Answer 1

\[V = \frac{ 1 }{ 3 }\pi*r^2*h\]

solve for the radius

Answer 2

\[r=\sqrt{\frac{ 3V }{ \pi*h }}\]

Answer 3

\(\bf
\textit{volume of a cone}=\cfrac{\pi r^2 h}{3}\qquad volume=251.2\qquad (h)eight=15
\\ \quad \\
251.2=\cfrac{\pi r^2\cdot 15}{3}\qquad \textit{solve for }r\)

Answer 4

Put in values for Volume V, and height h

Answer 5

Well, I don't think you have to show a derivation for the volume of a cone. That is given to you from the start. All i think you have to do is the algebra to solve for a variable.
