The formula for the volume of a cylinder is V = πr2h. The volume of a cylinder is three times the volume of a cone with the same
givi [52]
Since both objects are assumed to have the same volume, matching the formulas we'll get:

πr^{2}h = \frac{1}{3}πR^{2}h

Having both <span>π and h at both sides of the equation, we can ignore them, so:

</span><span>r^{2} = \frac{1}{3}R^{2}
</span>
And clearing R, according to the equation rules, we'll get:

\sqrt[2]{3 r^{2} } = R
