Question
Find the volume $ V $ of a cylinder if radius $r = 3.2\, \text{cm}$ and height $h = 7.5\, \text{cm}$.
Answer
$180\pi\, \text{cm}^3$
Explanation
To find volume $ V $ use formula:
$$ V = h ^{ 2 } \cdot r \cdot \pi$$After substituting $r = 3.2\, \text{cm}$ and $h = 7.5\, \text{cm}$ we have:
$$ V = 7.5\, \text{cm} ^{ 2 } \cdot 3.2\, \text{cm} \cdot \pi$$$$ V = 56.25\, \text{cm}^2 \cdot 3.2\, \text{cm} \cdot \pi $$$$ V = 180\pi\, \text{cm}^3 $$This page was created using
