The standard formula for the volume of a cone is V=πr2h3. If the cone is scaled proportionally by a factor of k, its volume beco
DaniilM [7]

The volume of a cone with base radius <em>r </em>and height <em>h</em> is

V = \frac 1 3 \pi r^2 h

What happens when we scale by <em>k </em>?

Let <em>V'</em> be the volume of a cone with radius <em>rk</em> and height <em>hk</em>

V' = \frac 1 3 \pi (rk)^2 (hk) = \frac 1 3 \pi r^2 k^2 h k = k^3 (\frac 1 3 \pi r^2 h) = k^3 V
