a military tent of height 8.25m is in the form of a right circular cylinder of base diameter 30m and height 5.5m surrmounted by a right circular cone of same base radius.find the lenght of the canvas used in making the tent if the base of the canvas is 1.5m.
radius of cone = radius of cylinder = 15m
height of cone = 8.25 - 5.5 = 2.75m
slant height2 = h2 + r2
l2 = (2.75)2 + (15)2
l2 = 232.5625
l = 15.25m
NOW,
area of canvas = c.s.a. of cone + c.s.a. of cylinder
= put value given above and solve it
height of cone = 8.25 - 5.5 = 2.75m
slant height2 = h2 + r2
l2 = (2.75)2 + (15)2
l2 = 232.5625
l = 15.25m
NOW,
area of canvas = c.s.a. of cone + c.s.a. of cylinder
= put value given above and solve it
