Find the incircle radius $ r $ of a hexagon if long diagonal $d = 24$.
Answer
$r = 6 \sqrt{ 3 }$
Explanation
STEP 1: find side $ a $
To find side $ a $ use formula:
$$ d = 2 \cdot a $$After substituting $ d = 24 $ we have:
$$ 24 = 2 \cdot a $$ $$ a = \dfrac{ 24 }{ 2 } $$ $$ a = 12 $$STEP 2: find incircle radius $ r $
To find incircle radius $ r $ use formula:
$$ r = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ a = 12 $ we have:
$$ r = \dfrac{ \sqrt{ 3 } \cdot 12 }{ 2 } $$$$ r = \dfrac{ 12 \sqrt{ 3 } }{ 2 } $$ $$ r = 6 \sqrt{ 3 } $$This page was created using
