Find the curved surface area of a cone with a radius of $6\text{cm}$ and slanted height of $8\text{cm}$.

Concept: We know the curved surface area of a cone $=\pi rl$.

Here, $r=6\text{cm}$ and $l=8\text{cm}$.

Now, the curved surface area of a cone  $=\pi rl$

$\Rightarrow \pi \times 6\times 8$

$\Rightarrow 48\pi$

Hence, the curved surface area of the given cone is $48\pi {\text{cm}}^2$.
