Explanation:

- The circumference \(C\) of a circle is calculated using the formula \(C = 2\pi r\), where \(r\) is the radius.

- Here, the circumference of the top of the bowl is given as 44 mm.

- We can set up the equation: \(44 = 2\pi r\).

- Solving for the radius \(r\), divide both sides by \(2\pi\):

$$

r = \frac{44}{2\pi} = \frac{22}{\pi}

$$

- Approximating \(\pi \approx 3.14\), we get:

$$

r \approx \frac{22}{3.14} \approx 7.006

$$

- The radius is approximately 7 mm.

- Option 1: 10 mm - Too large.

- Option 2: 7 mm - Matches our calculated radius.

- Option 3: 9 mm - Slightly larger.

- Option 4: 8 mm - Still larger than our result.

- The correct answer is Option 2: 7 mm.
