hiii!!!
here's Ur answer...
basically bottles are cylindrical so we will find it's CSA and TSA according to a cylinder.
given :-
radius of the bottle = 3.5m
height of the bottle = 35m
CSA of the bottle = 2πrh (as it's cylindrical)
= 2 × 22/7 × 3.5 × 35
= 44 × 3.5 × 5
= 770m²
TSA of the bottle = 2πr ( h + r )
= 2 × 22/7 × 3.5 ( 35 + 3.5 )
= 44/2 × 38.5
= 22 × 38.5
= 847cm²
hope this helps..!!
