A circus tent is cylindrical to a height of 3 m and conical above it. If its base radius is 52.5 m and the slant height of the conical portion is 53 m, find the area of canvas needed to make the tent. [Take π=227]
Height = h = 3 metres
Slant height = l = 53 metres
Radius = r = 52.5 metres
Area of canvas required = C.S.A of cone = πrl
= 227 × 52.5 × 53
= 8745 m²
