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
