Question

A conical tent is 10m high and the radius of its

base is 24m. Find the

(i) Slant height of the tent

(ii) Cost of the canvas required to make the tent, if

cost of 1m2

is Rs.50
only give write answer​

Answer 1

Step-by-step explanation:

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.
