The circumference of the base of a 10 m high conical tent is 44 m. Calculate the length of canvas used in making the tent if the canvas is 2 m wide.

answered-by-expert Expert Answer

Let h be the height of the conical tent and r be the radius of its base.

Circumference of the base = 44 m

2r = 44 m

Slant height, l=

Area of canvas = C.S.A of cone

L B = rl

L =

Thus, the length of the canvas used is 134.2 m.
