प्रश्न
A circus tent is cylindrical to a height of 3 meters and conical above it. If its diameter is 105 m and the slant height of the conical portion is 53 m, calculate the length of the canvas 5 m
wide to make the required tent.
उत्तर
Given diameter = 105 m
Radius = `105/2m=52.5m`
∴ Curved surface area of circus tent `= pirl+2 pirh`
=`22/7xx52.5xx53+2xx52.5xx3xx22/7`
= 8745+990
=` 9735m^2`
∴ `"Length of the canvas equation for tent = Area of canvas/width of canvas"`
`9735/5=1947m`
