Question

15. A conical tent 10 m high has radius of its base as 24m.calculate the cost of canvas cloth
required to make it @ Rs 140/m, if the canvas cloth is 2.6 m wide

Answer 1

$\huge\fbox \red{answer}$✍

Height,h=10 m

Radius,r=24 m

Let the slant height be l. Then,

l2=r2+h2

l2=676

l=26 m

Therefore, the slant height of the tent is 26 m.

Now,

CSA of tent = πrl=722×24×26=713728 m2

Hence, cost of canvas = 713728×70=137280 Rs
