There is a conical tent of height 84 m and base radius 13 m. If the cost of cloth is ₹40 per square metre, and the total cost of cloth used for the tent is ₹E, find the value of √((E/2041) − 4). (Use π = 3.14.) [In the original scan the extent of the radical sign is unclear; the key (8) requires −4 to be inside the root — transcribed as such here]
