$\large \boxed{\text{10 cm}}$

Step-by-step explanation:

The volume of the sphere must equal the volume of the cone.

$\begin{array}{rcll}V_{\text{sphere}} & = & V_{\text{cone}}&\\\dfrac{4}{3} \pi r^{3}& = & \dfrac{1}{3} \pi r^{2} h&\\4 \pi r^{3} & = & \pi r^{2} h &\text{Multiplied each side by 3}\\4r & = & h&\text{Divided each side by }\pi r^{2}\\h & = & 4r \times 2.5&\text{Substituted the value of }r\\& = & \textbf{10 cm}&\\\end{array}\\\text{The height of the cone must be $\large \boxed{\textbf{10 cm}}$}$
