Find the area of canvas required for a conical tent of height 24m and base radius 7m.

Explanation

let height `h=24m`& `r=7m`

so slant height `l=(r^2+h^2)^(1/2)`

`l=(7^2+24^2)^(1/2)`

`l=25m`

so curved surface area `=pirl`

`=pixx7xx25`

`=550m^2`

so , area of canvas required for a conical tent`=550m^2`
