To find the diameter of a circle given its circumference, you can use the formula for the circumference of a circle:
\[ C = \pi \times d \]
where:
- \( C \) is the circumference,
- \( \pi \) is approximately 3.14,
- \( d \) is the diameter.
You can rearrange the formula to solve for the diameter:
\[ d = \frac{C}{\pi} \]
Substituting the given values:
\[ d = \frac{15.7 \text{ ft}}{3.14} \approx 5.00 \text{ ft} \]
Therefore, the diameter of the circle is approximately **5.00 ft.**
\[ C = \pi \times d \]
where:
- \( C \) is the circumference,
- \( \pi \) is approximately 3.14,
- \( d \) is the diameter.
You can rearrange the formula to solve for the diameter:
\[ d = \frac{C}{\pi} \]
Substituting the given values:
\[ d = \frac{15.7 \text{ ft}}{3.14} \approx 5.00 \text{ ft} \]
Therefore, the diameter of the circle is approximately **5.00 ft.**
