Answer 2

Cost of canvas = Rs. 10870.20

Step-by-step explanation:

Tent has cylinder + cone of total height = 77 dm = 7.7m

Cylinder height = 44 dm and radius = 36/2 = 18 m

Cone radius = 18 m, height = 77-44 = 3.3 m

Slant height of the cone = root of (r² + h²) = root (18² + 3.3²) = root of 334.89 = 18.3m

Outer Surface area of cone = πrl = 22/7 * 18.3 * 18 = 1035.26 sq.m.

Outer Surface area of cylinder = 2πrh = 2 * 22/7 * 18 * 18.3 = 2070.51 sq.m

Surface area of tent = 2070.51 + 1035.26 = 3105.77 sq. m

Cost of canvas = 3.50 * 3105.77 = Rs. 10870.20
