Find the side $ a $ of a hexagon if incircle radius $r = \frac{ 63 }{ 200 }$.
Answer
$a = \frac{ 21 \sqrt{ 3}}{ 100 }$
Explanation
To find side $ a $ use formula:
$$ r = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ r = \frac{ 63 }{ 200 } $ we have:
$$ \frac{ 63 }{ 200 } = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$ $$ \sqrt{ 3 } \cdot a = \frac{ 63 }{ 200 } \cdot 2 $$ $$ \sqrt{ 3 } \cdot a = \frac{ 63 }{ 100 } $$ $$ a = \dfrac{ \frac{ 63 }{ 100 } }{ \sqrt{ 3 } } $$ $$ a = \frac{ 21 \sqrt{ 3}}{ 100 } $$This page was created using
