Answer 2

$\huge \bf \underline{ \underline{Correct \ Question}}$

Find curved surface area of a right circular cone whose slant height is 10 cm and has a base radius of 7 cm.

$\huge \bf \underline{ \underline{Answer}}$

Given:-

• Base radius (r) = 7cm
• Slant height (l) = 10cm

To Find:-

The curved surface area of the right circular cone

Solution:-

$= \pi \: \times \: r \times l \\ = \frac{22}{7} \times 7 \times 10 {cm}^{2} \\ = 220 {cm}^{2}$
