Find the incircle radius $ r $ of a hexagon if long diagonal $d = 4$.
Answer
$r = \sqrt{ 3 }$
Explanation
STEP 1: find side $ a $
To find side $ a $ use formula:
$$ d = 2 \cdot a $$After substituting $ d = 4 $ we have:
$$ 4 = 2 \cdot a $$ $$ a = \dfrac{ 4 }{ 2 } $$ $$ a = 2 $$STEP 2: find incircle radius $ r $
To find incircle radius $ r $ use formula:
$$ r = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ a = 2 $ we have:
$$ r = \dfrac{ \sqrt{ 3 } \cdot 2 }{ 2 } $$$$ r = \dfrac{ 2 \sqrt{ 3 } }{ 2 } $$ $$ r = \sqrt{ 3 } $$This page was created using
