Question 21 Mensuration Exercise 17.2

A conical tent is 10 m high and the radius of its base is 24 m.

Find :cost of the canvas required to make the tent, if the cost of 1 m2 canvas is Rs 70.



The shape of a cone is produced by stacking several triangles and spinning them around an axis. It has a total surface area and a curved surface area because it has a flat base.

Curved surface area = π rl

= (22/7)×24×26 = 13728/7 m2

Cost of 1 m2 canvas = Rs. 70

Total cost = (13728/7)×70

= Rs. 137280

Hence the cost of the canvas required to make the tent is Rs. 137280. M L Aggarwal - Understanding ICSE Mathematics - Class 10 chapter Mensuration Question 21 Solution image
