(2) A tent is in the form of a cylinder whose height is 5 m surmounted

1.	(2) A tent is in the form of a cylinder whose height is 5 m surmounted by a cone of equalbase. The diameter of base is 105 m. The slant height of cone is 60 m. Find the cost ofcloth at 15 per sq metre to make the tent.
Answer» Radius of base = 105/2 m Curved Surface Area of Cylinder = 2πrh => 2 * (π) * (105/2) * 5 = 525π Curved Surface Area of Cone = πrl => (π) * 105/2 * 60 = 3150 (π) Therefore total area of cloth required = 3150 (π) + 525 (π) = 3675 (π) = 11545.353 Therefore cost of making the tent = 11545.353/15 = ₹769.69

Answer»

Radius of base = 105/2 m

Curved Surface Area of Cylinder = 2πrh

=> 2 * (π) * (105/2) * 5 = 525π

Curved Surface Area of Cone = πrl

=> (π) * 105/2 * 60 = 3150 (π)

Therefore total area of cloth required = 3150 (π) + 525 (π) = 3675 (π) = 11545.353

Therefore cost of making the tent = 11545.353/15 = ₹769.69
