Question

A circus tent is cylindrical to a height of 4m and conical above it. If its diameter is 105 m and its slant height is 40 m, the total area of canvas required is

(a) $1760m^2$ (b) $2640m^2$

(c) $3960m^2$ (d) $7920m^2$

Answer 1

For cylinder
Diameter is 105 m
then radius is m
Now height=4 m



For cone
l=40 m and r=


Total surface area of the tent is the sum of lateral suface of cone and cylinder
=2πrh+πrl
=1320+6600
=7920 m²
