Diameter = 4 m
Slant height of the cone (l) = 2.8 m
Radius of the cone (r) = Radius of cylinder = 4/2 = 2 m
Height of the cylinder (h) = 2.1 m
We have to find out
(i) The area of the canvas used for making the tent.
(ii) The cost of the canvas of the tent at the rate of Rs 500 per m2.
Area of canvas =C.S.A of cone+ C.S.A of cylinder
ii) cost of canvas=Area*rate
The area of the cone =44m2
Cost of Canvas = Rs 22,000
