Find the Curved Surface Area $ CSA $ of a cone if radius $r = 1.21$ and slant height $l = 3.8$.
Answer
$CSA = 4.598\pi$
Explanation
To find Curved Surface Area $ CSA $ use formula:
$$ CSA = r \cdot l \cdot \pi$$After substituting $ r = 1.21 $ and $ l = 3.8 $ we have:
$$ CSA = 1.21 \cdot 3.8 \cdot \pi$$$$ CSA = 1.21 \cdot 3.8 \cdot \pi $$$$ CSA = 4.598\pi $$This page was created using
