Question

Find the curved surface area of a right circular cone whose slant height is 12cm and base radius is 7cm ?​

Answer 1

Answer:

curved surface area of cone equal to πrl

r=7cm

l = 12 cm

so πrl = 22/7×7×12

264cm2 (ans)

Answer 2

Answer:

264cm2

Step-by-step explanation:

Curver surface Area (CSA) of Cone=pi x r x l

where pi=22/7

r = Radius of cone = 7cm

l = slant height =12cm

CSA=(22/7 )x7x12

=22×12

=264cm2
