Find the radius $ r $ of a cone if height $h = 13$ and base area $AB = 8$.
Answer
$r = 1.5958$
Explanation
To find radius $ r $ use formula:
After substituting $ AB = 8 $ we have:
$$ AB = r^2 \cdot \pi $$ $$ r^2 \cdot \pi = 8 $$ $$ r = \sqrt{ \frac{ 8 }{\pi} } $$ $$ r \approx 1.5958 $$This page was created using
