Question
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 ₹120 per π m².Solution
The slant height of the conical tent =√ (122+92)= 15 cm Hence, the curved surface area of the conical tent = π × 9 × 15 = 135π m² Thus, the cost of the material = (135 π × 120) / π = Rs. 16,200 The cost of the material is Rs. 16,200.
