Question
Find the volume $ V $ of a cylinder if radius $r = 1.8\, \text{cm}$ and height $h = 4.2\, \text{cm}$.
Answer
$31.752\pi\, \text{cm}^3$
Explanation
To find volume $ V $ use formula:
$$ V = h ^{ 2 } \cdot r \cdot \pi$$After substituting $r = 1.8\, \text{cm}$ and $h = 4.2\, \text{cm}$ we have:
$$ V = 4.2\, \text{cm} ^{ 2 } \cdot 1.8\, \text{cm} \cdot \pi$$$$ V = 17.64\, \text{cm}^2 \cdot 1.8\, \text{cm} \cdot \pi $$$$ V = 31.752\pi\, \text{cm}^3 $$This page was created using
