1. What is Surface to Volume Ratio of Rotunda?

The Surface to Volume Ratio of Rotunda is a geometric property that represents the relationship between the total surface area and the volume of a rotunda shape. It is an important parameter in various mathematical and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ RA/V = \frac{\frac{1}{2} \times (5\sqrt{3} + \sqrt{10(65 + 29\sqrt{5})})}{\frac{h}{\sqrt{1 + \frac{2}{\sqrt{5}}}} \times \frac{1}{12} \times (45 + 17\sqrt{5})} \]

Where:

\( RA/V \) — Surface to Volume Ratio (m⁻¹)
\( h \) — Height of Rotunda (m)
\( \sqrt{} \) — Square root function

Explanation: The formula calculates the ratio of surface area to volume based on the height of the rotunda, incorporating mathematical constants and geometric relationships specific to this shape.
