Find the radius $ r $ of a cylinder if height $h = 20$ and volume $V = 7599$.
Answer
$r = 49.1817$
Explanation
To find radius $ r $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ V = 7599 $ and $ h = 20 $ we have:
$$ 7599 = 20 \cdot r ^{ 2 } \cdot \pi $$$$ r ^{ 2 } = \dfrac{ 7599}{ 20 \, \pi } $$$$ r ^{ 2 } = 2418.8389 $$$$ r = \sqrt{ 2418.8389 } $$$$ r = 49.1817 $$This page was created using
