Question

find the curved surface area of a cone whose base radius is 5.6 cm and slant height is 9 CM

Answer 1

Curved surface area=
$\pi \: rl$
=22/7x5.6x9

=22/7x50.4

=1108.8/7

=158.4 sq.cm

Answer 2

Thank you for asking this question, here is your answer:

In a cone the Radius of the base r  is equat to 5.6 cm

The slant height will be = 9 cm (l)

So the Curved surface area

= πrl =22/7 ×5.6 × 9

=22/7 ×50.4

=158.4 sq.cm

158.4 sqcm is the final answer for this question.
