Answer 1

Radius of conicaltent, `r = (5.4)/2`

                                     ` = 2.7 m`

                                     `= 27 dm`

Height of conical tent h = 42 dm

The volume of conical tent

`=1/3 pi r^2 h`

`=1/3 xx 22/7 xx 27 xx 27 xx  42 `

`= 22 xx 27 xx 27 xx 2`

`  = 32076 dm^3`

Since, each person is to be allowed 29.16 dm³,

Therefore,

`="volume of conical tent"/"place to be allow to each person"`

` = (32076)/(29.16)`

` = (3207600)/(2916)`

No. of person = 1100
