Let, inner radius of cylinder be ‘x’ cm.
4/3 π(6)3 = π × 32 (52 − x2)

or, (4 × 6 × 6 × 6) / (3 × 32) = 25 − x2 or, x2 = 25 − 9
or, x = 4 cm
Hence, thickness = 5 – 4 = 1 cm.

Z < L < W = N = K < A
For conclusion I -
L < W = N = K < A -
L < K < A
I. A > L (true) - It is clear that A is greater than L.
For conclusion II -
II. Z = A (false) Z = A is not confirm, so this is false.
Hence,only conclusion I follow.
