Question
Find the side $ a $ of a hexagon if incircle radius $r = 13.5\, \text{cm}$.
Answer
$15.5885\, \text{cm}$
Explanation
To find side $ a $ use formula:
$$ r = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $r = 13.5\, \text{cm}$ we have:
$$ 13.5\, \text{cm} = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$ $$ \sqrt{ 3 } \cdot a = 13.5\, \text{cm} \cdot 2 $$ $$ \sqrt{ 3 } \cdot a = 27\, \text{cm} $$ $$ a = \dfrac{ 27\, \text{cm} }{ \sqrt{ 3 } } $$ $$ a \approx 15.5885\, \text{cm} $$This page was created using
