Question

Find what length of Canvas 2 metre in witdh is needed to make a conical tent 20 metre and diameter and 42 and slant height allowing 10% for stitching also find cost of Canvas @ rupees 80 per metre​

Answer 1

726 m canvas length required to make conicl tent & cost = Rs 58,080‬

Step-by-step explanation:

Assuming No cloth on Bottom

Conical tent curved area = πRL

R = r = 20/2 = 10 m

L = Slant Height = 42 m

= (22/7) * 10 * 42

= 1320 m²

allowing 10% for stitching

=> Total Cloth Required = 1320 + (10/100)1320

= 1452 m²

Width of canvas = 2m

=> length of canvas Required = 1452/2  = 726 m

cost of Canvas @ rupees 80 per meter​ = 726 * 80  = Rs 58,080‬

Assuming cloth is at bottom also then add Area of base = πR² = (22/7) * 10² and solve as done above.
