Find the side $ a $ of a square if circumcircle radius $R = 147$.
Answer
$a = 147 \sqrt{ 2 }$
Explanation
To find side $ a $ use formula:
$$ R = \dfrac{ \sqrt{ 2 } \cdot a }{ 2 } $$After substituting $ R = 147 $ we have:
$$ 147 = \dfrac{ \sqrt{ 2 } \cdot a }{ 2 } $$ $$ \sqrt{ 2 } \cdot a = 147 \cdot 2 $$ $$ \sqrt{ 2 } \cdot a = 294 $$ $$ a = \dfrac{ 294 }{ \sqrt{ 2 } } $$ $$ a = 147 \sqrt{ 2 } $$This page was created using
