Find the radius $ r $ of a cylinder if height $h = 31$ and volume $V = 4700$.
Answer
$r = 38.6789$
Explanation
To find radius $ r $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ V = 4700 $ and $ h = 31 $ we have:
$$ 4700 = 31 \cdot r ^{ 2 } \cdot \pi $$$$ r ^{ 2 } = \dfrac{ 4700}{ 31 \, \pi } $$$$ r ^{ 2 } = 1496.0577 $$$$ r = \sqrt{ 1496.0577 } $$$$ r = 38.6789 $$This page was created using
