diameter= 10.5cm then radius= 5.25cm
slant height= 10
then curved surface area=Πrl
= 3.14*5.25*10=165.85 sq.cm
slant height= 10
then curved surface area=Πrl
= 3.14*5.25*10=165.85 sq.cm

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 ☺️
