A rectangle of length, 14 cm and breadth, 7 cm is rotated about its shorter side to form a cylinder. What is the volume (in cm3) of the cylinder so generated? (Take π = 22722\over7)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 4312.

Height of cylinder = 7 cm

Radius of the cylinder = 14 cm
