How many square metres of canvas is required for a conical tent whose height is 3.5 m and the base is 12 m? |
|
Answer» Given height of a conical tent, h = 3.5 m and radius of the base of a conical tent , r= 12m Slant, height , `l = sqrt(h^(2) + r^(2)) = sqrt((3.5)+ (12)^(2))` `" "=sqrt(12.25 + 144)` `= sqrt(15625)= 12.5m` `therefore` Canvas required = Curved surface area of the cone (conical tent) `= pirl =(22)/(7) xx 12 xx12.5` `= 471.42m^(2)` Hence, the canvas required to makes a conical tent is `471.42m^(2)` |
