Find the radius $ r $ of a circle if circumference $C = \frac{ 12089 }{ 125 }$.
Answer
$r = 15.3922$
Explanation
To find radius $ r $ use formula:
$$ C = 2 \cdot r \cdot \pi $$After substituting $ C = \frac{ 12089 }{ 125 } $ we have:
$$ \frac{ 12089 }{ 125 } = 2 \cdot r \cdot \pi $$ $$ r = \dfrac{ \frac{ 12089 }{ 125 } }{ 2 \pi } $$ $$ r \approx 15.3922 $$This page was created using
