Find the circumcircle radius $ R $ of a hexagon if short diagonal $s = \frac{ 3 }{ 4 }$.
Answer
$R = \frac{\sqrt{ 3 }}{ 4 }$
Explanation
STEP 1: find side $ a $
To find side $ a $ use formula:
$$ s = \sqrt{ 3 } \cdot a $$After substituting $ s = \frac{ 3 }{ 4 } $ we have:
$$ \frac{ 3 }{ 4 } = \sqrt{ 3 } \cdot a $$ $$ a = \dfrac{ \frac{ 3 }{ 4 } }{ \sqrt{ 3 } } $$ $$ a = \frac{\sqrt{ 3 }}{ 4 } $$STEP 2:
The radius of the circumcircle is equal the side of the hexagon. $$ R = \frac{\sqrt{ 3 }}{ 4 } $$
