Please answer me fastly​

Answer 1

Step-by-step explanation:

radius of cylinder and cone :14m

height of cylender:3m

total height of tent:13.5m

height of conical part :13.5-3=10.5

ar(inner part) =CSA of cone + CSA of cylinder

πrl+2 πrh

πr(l+2r)

π*14(17.5+2*3) l=√196+110.25

=√306.5=17.5

14*22/7(23.5)

1034msqure

cost=1034*2=2068rupees
