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 m2 canvas is Rs. 70, find the cost of the canvas required to make the tent.
We have,
Radius of base of tent = r= 24 m
Vertical height = h = 10 m
∴slant height = l =
= 
= 26m
∴ Cost of canvas required = Rs.
= Rs. 137280
