The radius of the base of a conical tent is 5m. If the tent is 12 m high then the area of the canvas required in making the tent is .........
Radius of conical tent = r = 5 m
Height of conical tent = h = 12 m
Lateral height = $$l = \sqrt{r^2 + h^2} =Â \sqrt{5^2 + 12^2} = 13$$ cm
Aarea of the canvas required in making the tent = Curved Surface area = $$\pi rl = \pi * 5 * 13 = 65 \pi m^2$$Â
