Solution :
Base radius (r) = 7 cm
slant height (l) = 10 cm
Formula for curved surface area of a cone is = πrl
now solving the question using given formula
πrl = (22/7)*7*10
22*10= 220cm square
Hope it helps.....

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.
