A conical tent has base radius 7 m and vertical height 24 m. Canvas for it costs ₹50 per m², and 10% extra canvas must be bought for stitching and wastage. Find the total cost in rupees. Take π = 22/7.

Question

Accepted Answer

30250. Slant height = √(24² + 7²) = 25 m, so the curved surface = (22/7) × 7 × 25 = 550 m². With the 10% allowance, canvas bought = 550 × 1.1 = 605 m². Cost = 605 × 50 = ₹30250.
