Question

A tent of cloth is cylindrical up to 1 m height and conical above it of the same radius of base . If the diameter of tent is 6 m and the slant height of conical part is 5 m, find the cloth required to make this tent

Answer 1

Diameter of base 2r=6m
`r=(6)/(2) =3m`
Height of cylindrical path h=1 m
Slant height of conical part l=5m
Cloth required in tent =`2pirh+pirl`
`=pir(2h+l)`
`=(22)/(7)xx3(2xx1+5)=66m^(2)`
