The radius of a cone is $7 c m$ and its slant height is $10 c m$ . Calculate the curved surface area of the cone.

Given, radius $r = 7 c m$
and slant height $l = 10 c m$ .

Then, curved surface area of cone $= π r l$
$= \frac{22}{7} \times 7 \times 10$
$= 220 s q . c m$ .

Hence, the required curved surface area of cone $= 220 s q . c m$ .

The radius of a cone is 7 cm and its slant height is 10 cm. Calculate the curved surface area of the cone.

Given, radius r=7cmand slant height l=10cm.Then, curved surface area of cone =πrl=227×7×10=220 sq.cm.Hence, the required curved surface area of cone =220 sq.cm.
