Question
![**Problem 14:** Find the circumference of the circle. Use 3.14 for the value of π. Round your answer to the nearest tenth.
- **A. 116.8 in**
- **B. 63.4 in**
- **C. 58.4 in**
- **D. 64.7 in**
**Diagram Description:**
The diagram is a circle with a labeled radius of 9.3 inches.
**Work Box:**
An empty box labeled "Work:" is provided for calculations.
**Solution Steps:**
1. **Identify the radius (r):** 9.3 inches
2. **Use the formula for circumference (C):**
\[
C = 2\pi r
\]
3. **Substitute the values into the formula:**
\[
C = 2 \times 3.14 \times 9.3
\]
4. **Calculate:**
\[
C = 58.404
\]
5. **Round to the nearest tenth:** 58.4 inches
Thus, the correct answer is **C. 58.4 in**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc4b20233-c0ae-4fc6-b8f4-78747967c774%2F9a843877-4885-4875-ad61-f3859425f651%2Fm4pavnl_processed.jpeg&w=3840&q=75)
