Find the diameter $ d $ of a circle if area $A = 10$.
Answer
$d = 3.5682$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
After substituting $ A = 10 $ we have:
$$ A = r^2 \cdot \pi $$ $$ r^2 \cdot \pi = 10 $$ $$ r = \sqrt{ \frac{ 10 }{\pi} } $$ $$ r \approx 1.7841 $$STEP 2: find diameter $ d $
To find diameter $ d $ use formula:
$$ d = 2 \cdot r $$After substituting $ r = 1.7841 $ we have:
$$ d = 2 \cdot 1.7841 $$ $$ d \approx 3.5682 $$This page was created using
