Question
Find the Curved Surface Area $ CSA $ of a cone if radius $r = 13\, \text{cm}$ and slant height $l = 31\, \text{cm}$.
Answer
$403\pi\, \text{cm}^2$
Explanation
To find Curved Surface Area $ CSA $ use formula:
$$ CSA = l \cdot r \cdot \pi$$After substituting $r = 13\, \text{cm}$ and $l = 31\, \text{cm}$ we have:
$$ CSA = 31\, \text{cm} \cdot 13\, \text{cm} \cdot \pi$$$$ CSA = 31\, \text{cm} \cdot 13\, \text{cm} \cdot \pi $$$$ CSA = 403\pi\, \text{cm}^2 $$This page was created using
