Ratio of the circumference and the diameter of a circle is more than 3.

Answer

To solve the problem of determining whether the ratio of the circumference to the diameter of a circle is more than 3, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- The **circumference** (C) of a circle is given by the formula:
\[ C = 2\pi r \]
where \( r \) is the radius of the circle.
- The **diameter** (D) of a circle is given by the formula:
\[ D = 2r \]

2. **Set Up the Ratio**:
- We need to find the ratio of the circumference to the diameter:
\[ \text{Ratio} = \frac{C}{D} \]

3. **Substitute the Formulas**:
- Substitute the formulas for circumference and diameter into the ratio:
\[ \text{Ratio} = \frac{2\pi r}{2r} \]

4. **Simplify the Ratio**:
- The \( 2r \) in the numerator and denominator cancels out:
\[ \text{Ratio} = \frac{2\pi r}{2r} = \pi \]

5. **Evaluate the Value of Pi**:
- The value of \( \pi \) (pi) is approximately \( 3.14 \).

6. **Compare with 3**:
- Since \( \pi \approx 3.14 \), we can conclude that:
\[ \pi > 3 \]

7. **Conclusion**:
- Therefore, the statement that the ratio of the circumference to the diameter of a circle is more than 3 is **true**.
