Find the side $ a $ of a square if circumcircle radius $R = 6$.
Answer
$a = 6 \sqrt{ 2 }$
Explanation
To find side $ a $ use formula:
$$ R = \dfrac{ \sqrt{ 2 } \cdot a }{ 2 } $$After substituting $ R = 6 $ we have:
$$ 6 = \dfrac{ \sqrt{ 2 } \cdot a }{ 2 } $$ $$ \sqrt{ 2 } \cdot a = 6 \cdot 2 $$ $$ \sqrt{ 2 } \cdot a = 12 $$ $$ a = \dfrac{ 12 }{ \sqrt{ 2 } } $$ $$ a = 6 \sqrt{ 2 } $$This page was created using
