Question

The height of a tent is 9m.its base diameter is 24m.what is its slant height? Find the cost of canvas cloth required if it costs rs14 per sq.m.

Answer 1

tent shape like cone
so slant height=root {r^2+h^2}
here given diameter=24m
so, radius=12m
hence slant height =root {(12)^2+(9)^2}
=root {225}=15m
now
area of canvas clothes=pi.r.l
l is here slant height
hence area of clothes=22/7 x 12 x 15
hence cost of canvas clothes=area of canvas clothes x rate
=22/7 x 12 x 15 x 14=7920 Rs
