Find the Curved Surface Area $ CSA $ of a cone if radius $r = 2$ and slant height $l = 7$.
Answer
$CSA = 14\pi$
Explanation
To find Curved Surface Area $ CSA $ use formula:
$$ CSA = r \cdot l \cdot \pi$$After substituting $ r = 2 $ and $ l = 7 $ we have:
$$ CSA = 2 \cdot 7 \cdot \pi$$$$ CSA = 2 \cdot 7 \cdot \pi $$$$ CSA = 14\pi $$This page was created using
