Explanation:

- Let the radius of the smaller circle be 14v2 cm.

- The diameter of the smaller circle equals the side of the square, as it touches all sides.

- Thus, the side of the square is 28v2 cm (double the radius).

- The diagonal of the square, which is the diameter of the larger circle, is calculated using the formula: side × v2.

- Therefore, the diagonal is 28v2 × v2 = 28 × 2 = 56 cm.

- Circumference of the larger circle = p × diameter = p × 56 cm.

- Using p ˜ 22/7, the circumference ˜ (22/7) × 56 cm = 176 cm.

- ? Option 1: 176 cm is correct.
