Answer 2

The curved surface area of right circular cone is $330cm^{2}$.

Step-by-step explanation:

We have,

Slant height(l) = 10 cm and Base radius(r) = 10.5 cm

To find, the curved surface area of right circular cone = ?

We know that,

The curved surface area of right circular cone $= \pi rl$

$= \dfrac{22}{7} \times 10.5\times 10cm^{2}$

$=22\times 1.5\times 10cm^{2}$

$=22\times 15 cm^{2}$

= 330 $cm^{2}$

Hence, the curved surface area of right circular cone is $330cm^{2}$.
