Question

I have a problem where they want me to find the radius of a cone with a volume of 60 and a height of 21?

Answer 1

\(\bf \textit{volume of a cone}=\cfrac{\pi {\color{blue}{ r}}^2 h}{3}\qquad h=height=21\qquad volume=60
\\ \quad \\
60=\cfrac{\pi {\color{blue}{ r}}^2 \cdot 21}{3}\)

solve for "r", or radius
