Find the radius $ r $ of a circle if circumference $C = 1800$.
Answer
$r = 286.4789$
Explanation
To find radius $ r $ use formula:
$$ C = 2 \cdot r \cdot \pi $$After substituting $ C = 1800 $ we have:
$$ 1800 = 2 \cdot r \cdot \pi $$ $$ r = \dfrac{ 1800 }{ 2 \pi } $$ $$ r \approx 286.4789 $$This page was created using
