There is a tent in a conical shape. The slant height of the tent is 14 m. If the curved surface area of the tent is 308 m2 , then what is the base area of the tent? (Take π=227)
The curved surface area of a cone is πrl where r is radius and l is slant height of the conical tent.
Given, curved surface area of the conical tent =308 m2 and slant height, l=14 m
∴πrl=308
⇒227×r×14=308
⇒r=308×722×14=7 m
∴ Base area =πr2
=227×72
=154 m2
