Question

A tent is in the shape of cylinder surrounded by a conical
top. If the height and diameter of the cylindrical part are
2.1m and 4m respecrtively and the slant height of the top
is 2.8m. Find the area of the canvas used for making the
tent. Also find the cost of the canvas of the tent at the rate
of Rs. 500 per m². (Note that the base of the tent will not
be covered with canvas)​

Answer 1

Step-by-step explanation:

• h=2.1m , d=4m so , r=2m , l = 2.8m . So, C.SA of Canvas (cone) = πrl = 22/7*2*2.8=22*0.8=17.6 mSq. Cost of Canvas = 500*17.6=8800.0 =8800 Rupees.
