Answer 1

Answer: Rs 2750

Step-by-step explanation:

Let the slant height of the cone be 'l' meters.

height = 24 m and diameter = 14 m or radius = 7 m.

Therefore, Slant height, l = √(r2 + h2) = √(49 + 576) = √625 = 25 m

CSA of the cone = πrl = (22/7) x 7 x 25 = 550 m2

Area of the cloth used = 550 m2

given, width of the cloth = 5 m

Length of the cloth used = Area/Width = 550 / 5 = 110 m.

Total cost, at the rate of ₹25/m = length×price =110×25 = ₹2750.
