Diameter=10.5cm
Radius =10.5/2
Slant height = cm
Therefore curved surface area=pie rl
=22/7 into 10.5 upon 2 into 10
=165cm^2
Radius =10.5/2
Slant height = cm
Therefore curved surface area=pie rl
=22/7 into 10.5 upon 2 into 10
=165cm^2

Answer:
Radius of the base of cone = diameter/ 2 = (10.5/2)cm = 5.25cm
Slant height of cone, say l = 10 cm
CSA of cone is = πrl
= (22/7)×5.25×10 = 165
Therefore, the curved surface area of the cone is 165 cm2.
hope will be helpful ☺️
