28. A military tent of height 8.25 m is in the form of a right circular cylinder of base diameter30 m and height 5.5 m surmounted by a right circular cone of same base radius. Find thelength of the canvas used in making the tent, if the breadth of the canvas is 1.5 m. |
|
Answer» Height of the cone = 8.25 - 5.5= 2.75 mSlant height of the cone(l)= Under root h^2 + r^2 = 15.25surfacearea of cone= pie x r x l = 3.14 x 15 x 15.25=718.3surfacearea of cylinder = 2 x pie x r x h = 2 x 3.14 x 15 x 5.5= 518.1area of canvas used = 718.3 + 518.1 =1236.4length of canvas = 1236.4/1.5= 824.3 m |
