Question

a conical tent of base radius 7m and height 24m find the cost of canvas used in making this tent at rate Rs.70per m square​

Answer 1

Answer:

Here is your ans.....

Step-by-step explanation:

Given:--- radius(r)= 7m

height(h)= 24m

Now,

Let the slant height be l. Then,

L^2=h^2+r^2

=(24)^2+(7)^2

=576+49

=625

l=25m

Thus,

Curved Surface Area of the tent =22/7*7*25

=550m^2.

Given that:----

cost of 1 m sq. canvas=Rs.70

Therefore,

cost of 550 m sq.=(550*70)=Rs.38500.
