alleryThe volume of a thin cylindrical shell equals what?
A2π × inner radius × height × thickness
B2π × mean radius × height × thickness
C4π × mean radius × height × thickness
Dπ × mean radius² × height × thickness
Answer & Solution
Correct answer: B. 2π × mean radius × height × thickness
Unrolling the shell gives a thin slab of length 2 pi times the average radius, with the given height and thickness.
