Question

A conical tent is 10 m high and the radius of its base is 24 m. Find(i) slant height of the tent.(ii) cost of the canvas required to make the tent, if the cost of `1 m^2`canvas is Rs 70.

Answer 1

Slant height of cone`=l=sqrt(r^2+h^2)`
therefore`=>l=sqrt(676)=26cm`
Area of covered area=`pi xx rxxl=22/7 xx 24 xx 26=1961.143(m)^2`
Total cost to make tent`=>1961.143(m)^2xx 70=Rs.137280.`
