Answer:
∵ Diameter of the base =10.5cm
∴ Radius of the base (r)= 10.5/2cm
(r)=5.25cm
Slant height (l)=10cm
∴ Curved surface area of the cone.
=πrl= 22/7×5.25×10=165cm²
I hope it help you..

Answer:
Diameter of the base of the cone = 10.5cm
r = 10.5/2=5.25
slant height, l = 10cm
Curved surface area of cone = πrl
= 22/7 × 5.25 × 10
= 22 × 0.75 × 10
= 22×7.5
= 165cm²
I hope it helps you.
