The radius of a cone is $7\ cm$ and area of curved surface is $176\ cm^2$. Find the slant height.

 Given:

The radius of a cone is $7\ cm$ and area of curved surface is $176\ cm^2$.

To do:

We have to find the slant height.

Solution:

The curved surface area of the cone $= 176\ cm^2$

Radius of the base $(r) = 1\ cm^2$

Therefore,

Slant height of the cone $(l)=\frac{\text { Area }}{\pi r}$

$=\frac{176 \times 7}{22 \times 7}$

$=8 \mathrm{~cm}$
