A circus tent is

The Circus tent is made as a combination of cylinder and cone on top.

Height of cylindrical part of tent = h = 3 m

Base radius of tent = r = 52.5 m

Area of canvas required for cylindrical part of tent = 2πrh

= 2 × 22/7 × 52.5 × 3 m²

= 990 m²

Slant height of cone = l = 53 m

Area of canvas required for conical part of the tent = πrl

= 22/7 × 52.5 × 53 m²

= 8745 m²

Area of canvas required to make the tent = Area of canvas required for cylindrical part of tent + Area of canvas required for conical part of tent

Area of canvas required to make the tent = 990 + 8745 m² = 9735 m²
