Question

the diameter of a cone is 14 cm and d its slant height is 9cm find its C.S.A.​

Answer 1

Answer:

C.S.A of cone = 198 cm.sq.

Step-by-step explanation:

Radius of cone = D/2

                         = 14/2

                         = 7 cm.

C.S.A. of cone = Pi x r x l

                        = 22/7 x 7 x 9

                        = 22 x 9

                        = 198 cm.sq.
