Question
Find the lateral area $ AL $ of a cylinder if radius $r = 8\, \text{cm}$ and height $h = 12\, \text{cm}$.
Answer
$192\pi\, \text{cm}^2$
Explanation
To find lateral area $ AL $ use formula:
$$ AL = 2 \cdot h \cdot r \cdot \pi $$After substituting $r = 8\, \text{cm}$ and $h = 12\, \text{cm}$ we have:
$$ AL = 24\, \text{cm} \cdot 8\, \text{cm} \cdot \pi $$$$ AL = 192\pi\, \text{cm}^2 $$This page was created using
