Question

a tent is in the form of cylinder whise height is 5m surmounted by a cone of equal base.diameter of base is 105m the slant height of cone is 60m.find the cost of cloth at ruppes 15 per sq meters to make a tent

Answer 1

Answer:

₹769.69

Step-by-step explanation:

Radius of base = 105/2 m

Curved Surface Area of Cylinder = $2\pi rh$

=> 2 * ($\pi$) * (105/2) * 5 = 525$\pi$

Curved Surface Area of Cone = $\pi rl$

=> ($\pi$) * 105/2 * 60 = 3150  ($\pi$)

Therefore total area of cloth required = 3150 ($\pi$)  + 525  ($\pi$)  = 3675  ($\pi$) = 11545.353 $m^{2}$

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