Question:

Find the curved surface area of a cone, if its slant height is 60 cm and the radius of its base is 21 cm.

Explanation:

Given:

Slant height of cone (r)= 60 cm.

Radius of base of cone (l) = 21 cm

Curved surface area of cone

= πrl

= 22/7×21×60

=3960 cm^2

Answer 2

Answer:

3960 sq.cm

Step-by-step explanation:

C.S.A of cone = 22 x l x r / 7                            ( l = slant height )

                       = 22 x 21 x 60 / 7

                       = 22 x 180

                       = 3960 sq.cm
