A conical tent is 10 m high and the radius of its base is 24 m. Find the slant height of the tent. If the cost of 1 2 m canvas is Rs. 70, find the cost of the canvas required to make the tent.
Height of conical tent (h)=10m
Radius of conical tent (r) = 24m
Let slant height of conical tent be l
Thus, the slant height of the conical tent is 26 .
(ii) Given that
Slant height (l)=26
CSA of tent =`pirl=22/7xx24xx26=13728/7m^2`
Cost of `1m^2`canvas S=Rs.70.
`Cost of 13728/7m^2 canvas= 13728/7xx10`
Thus, the cost of canvas required to make the tent is Rs. 137280.
