Question

If the diameter of a cone is 14 cm & its slant height is 9 cm,then its curved surface area will be ___________ Pleaseee tell meeeeeeee.........

Answer 1

curved surface area of cone =$\pi rl$

where ,r = 7cm

  l = 9 cm

so, csa of cone =  $\pi * 9*7$

   ===>  $\pi *63$

===> 22 *63/7

==>22*9

==>198 $cm^{2}$

hope this will helps u.........................

Answer 2

Step-by-step explanation:

TheCurved surface area of a cone =πrl

Radius=D/2 =7

CSA of cone=22/7*7*9

198cm²
