Find the radius $ r $ of a cone if volume $V = 198\, \text{cm}$ and base area $AB = 22\, \text{cm}$.
Answer
$2.6463$
Explanation
To find radius $ r $ use formula:
After substituting $AB = 22\, \text{cm}$ we have:
$$ AB = r^2 \cdot \pi $$ $$ r^2 \cdot \pi = 22\, \text{cm} $$ $$ r = \sqrt{ \frac{ 22\, \text{cm} }{\pi} } $$ $$ r \approx 2.6463 $$This page was created using
