Find the circumference $ C $ of a circle if radius $r = \frac{ 129 }{ 5 }$.
Answer
$C = \frac{ 258 }{ 5 }\pi$
Explanation
To find circumference $ C $ use formula:
$$ C = 2 \cdot r \cdot \pi $$After substituting $ r = \frac{ 129 }{ 5 } $ we have:
$$ C = 2 \cdot \frac{ 129 }{ 5 } \cdot \pi $$ $$ C = \frac{ 258 }{ 5 }\pi $$This page was created using
