Answer 2

Step-by-step explanation:

Given height h = 84 cm

And radius r = 35 cm

We know that slant height l = root of (r^2 +h^2)

= root of ( (84^2)+(35^2))

= root of (1225+7056)

= root 8281

= 91 cm

Curved surface area or lateral surface area of a right circular cone = pi * rl

= (22/7) * 35 * 91

= 10,010 cm^2
