Answer:

When a sector of radius R=21 cm & aperture angle θ=90∘=π/2 is folded to form curved surface of a right circular cone then the area of curved surface of cone becomes equal to the area of sector

hence, the total surface area of cone including inside & outside curved surfaces formed by sector

=2(12θR2)

=2(12π2(21)2)

=12π(441)

=12×227×441

=693 cm2
