Find the area $ A $ of a circle if radius $r = \frac{ 132 }{ 5 }$.
Answer
$A = \frac{ 17424 }{ 25 }\pi$
Explanation
To find area $ A $ use formula:
$$ A = r^2 \cdot \pi $$After substituting $ r = \frac{ 132 }{ 5 } $ we have:
$$ A = \left(\frac{ 132 }{ 5 }\right)^2 \cdot \pi $$ $$ A = \frac{ 17424 }{ 25 } \cdot \pi $$This page was created using
