(a)
12m
(b) 15m
(C)
18m
(d)
24m​

Answer 1

Answer:

Step-by-step explanation:

Height,h=10 m

Radius,r=24 m

Let the slant height be l. Then,

l  

2

=r  

2

+h  

2

 

l  

2

=676

l=26 m

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

Now,

CSA of tent = πrl=

22

​

×24×26=

13728

​

 m

Hence, cost of canvas =
