Find the radius $ r $ of a circle if area $A = \frac{ 2573 }{ 100 }$.
Answer
$r = 2.8618$
Explanation
To find radius $ r $ use formula:
After substituting $ A = \frac{ 2573 }{ 100 } $ we have:
$$ A = r^2 \cdot \pi $$ $$ r^2 \cdot \pi = \frac{ 2573 }{ 100 } $$ $$ r = \sqrt{ \frac{ \frac{ 2573 }{ 100 } }{\pi} } $$ $$ r \approx 2.8618 $$This page was created using
