Cost of canvas = Rs. 79,200
Step-by-step explanation:
Diameter of the base = 100m
Radius of cyclinder = radius of cone = 50m
Height of cylinder = 3.3m
Slant height of cone = 56.4m
Cost of canvas per m² = Rs. 8.
Canvas required = curved surface area of cylinder + curved surface area cone
= 2πrh + πLr
= 22/7 [ (2 * 50 * 3.3) + (56.4 * 50) ]
= 1037.14 + 8862.86
= 9900 m²
Cost of canvas = 9900 * 8 = Rs. 79,200
