# Acorn Spheroform

Algebra Level 2

$A = \left ( \dfrac{710}{113} - \dfrac{252050}{76614} \right) R^2 \qquad \qquad V = \left( \dfrac{710}{339} - \dfrac{126025}{76614} \right) R^3$

Let $$A$$ and $$V$$ denote the area and volume of a Reuleaux triangle spheroform, respectively, where $$R$$ is a parameter.

Find the value of $$R$$ satisfying $$\dfrac AV = \dfrac{646}{97} \approx 6.65979\ldots$$.
