#### Question

The circumference of the base of a 10 m height conical tent is 44 metres. Calculate the length of canvas used in making the tent if width of canvas is 2 m. (Use it 𝜋= 22/7).

#### Solution

WKT, CSA of cone = `pirl`

Given circumference=`2pir`

⇒` 2xx22/7xxr=44⇒ r/7=1⇒ r=7m`

`∴ L= sqrt(r^2+h^2)=sqrt(7^2+10^2)=sqrt149m`

`∴ CSA of tent=pirl=22/7xxsqrt149=22sqrt149`

∴ The length of can vas used in making tent

`="Area of canvas"/"width of canvas"`

`22sqrt149/2=11sqrt49`

= 134.2m
