The radius of the base of a conical tent is 9 m and its
height is 12 m, find the cost of the material needed to make it if it costs ₹100 per π m².Solution
Hence, the curved surface area of the conical tent = π × 9 × 15 = 135π m² Thus, the cost of the material = (135 π × 100) / π = Rs. 13,500 .. The cost of the material is Rs. 13,500.
