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
