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