Find the volume $ V $ of a cylinder if radius $r = 1.8$ and height $h = 4.2$.
Answer
$V = 13.608\pi$
Explanation
To find volume $ V $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ r = 1.8 $ and $ h = 4.2 $ we have:
$$ V = 1.8 ^{ 2 } \cdot 4.2 \cdot \pi$$$$ V = 3.24 \cdot 4.2 \cdot \pi $$$$ V = 13.608\pi $$This page was created using
