Find the slant height $ l $ of a cone if radius $r = 2.3$ and Curved Surface Area $CSA = 14.4513$.
Answer
$l = 2$
Explanation
To find slant height $ l $ use formula:
$$ CSA = r \cdot l \cdot \pi $$After substituting $ CSA = 14.4513 $ and $ r = 2.3 $ we have:
$$ 14.4513 = 2.3 \cdot l \cdot \pi $$$$ l = \dfrac{ 14.4513 }{ 2.3 \, \pi} $$$$ l = 2 $$This page was created using
