The diameter of a cylinder is measured using a vernier caliper with no zero error. It is found that the zero of the vernier scale lies between $5.10 cm$ and $5.15 cm$ of the main scale. The vernier scale have $50$ divisions equivalent to $2.45 cm$ . The $24^{th}$ division of the vernier scale exactly coincides with one of the main scale divisions. The diameter of the cylinder is,
