The circumference of the base of a 10m high conical tent is 44 metres. Calculate the length of canvas used in making the tent if width of canvas is 2m. `(U s epi=(22)/7)`

Explanation

given height `h=10m`

circumference of
conical tent` = 44 m`
`2pir=44`
`r=7cm`
`l=(r^2+h^2)^(1/2)`
`l=(149)^(1/2)`
curved surface area`=pirl`
`=pixx7xx(149)^(1/2)`
so total area of canvas used`=curved area of cone`
`pixx7xx(149)^(1/2)=lengthxx2`
length `=(7pi)/2xx(149)^(1/2)`

`=11xx(149)^(1/2)m`
