\text { An architect's design for a building includes some pillars in the shape of hyperbolas. The curve can be } \text { modeled by the equation }-\frac{x^{2}}{0.0625}-\frac{y^{2}}{0.1875}=1 \text { Where units are in meters. If the heights of the pillars are same as height of the latus rectum of the } \text { hyperbola, find the diameter of the top of the pillars. }
