Question

Radius of bottle is 3.5m and height is 35m find CSA&TSA

Answer 1

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..!!
