Find the diameter $ d $ of a circle if area $A = \frac{ 7693 }{ 2500 }$.
Answer
$d = 1.9794$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
After substituting $ A = \frac{ 7693 }{ 2500 } $ we have:
$$ A = r^2 \cdot \pi $$ $$ r^2 \cdot \pi = \frac{ 7693 }{ 2500 } $$ $$ r = \sqrt{ \frac{ \frac{ 7693 }{ 2500 } }{\pi} } $$ $$ r \approx 0.9897 $$STEP 2: find diameter $ d $
To find diameter $ d $ use formula:
$$ d = 2 \cdot r $$After substituting $ r = 0.9897 $ we have:
$$ d = 2 \cdot 0.9897 $$ $$ d \approx 1.9794 $$This page was created using
