To find the radius of a circular flower bed with an area of approximately 492 square feet, we can use the formula for the area of a circle:
\[
A = \pi r^2
\]
Where:
- \( A \) is the area,
- \( r \) is the radius,
- \( \pi \) is approximately 3.14.
We can rearrange the formula to solve for the radius \( r \):
\[
r = \sqrt{\frac{A}{\pi}}
\]
Substituting in the area:
\[
r = \sqrt{\frac{492}{\pi}} \approx \sqrt{\frac{492}{3.14}} \approx \sqrt{156.96} \approx 12.53 \text{ feet}
\]
Now we can match this with the provided options:
A. 10 feet
B. 11.25 feet
C. 12.5 feet
D. 13.35 feet
E. 14.2 feet
The closest option to our calculated value of approximately 12.5 feet is **C. 12.5 feet**.
\[
A = \pi r^2
\]
Where:
- \( A \) is the area,
- \( r \) is the radius,
- \( \pi \) is approximately 3.14.
We can rearrange the formula to solve for the radius \( r \):
\[
r = \sqrt{\frac{A}{\pi}}
\]
Substituting in the area:
\[
r = \sqrt{\frac{492}{\pi}} \approx \sqrt{\frac{492}{3.14}} \approx \sqrt{156.96} \approx 12.53 \text{ feet}
\]
Now we can match this with the provided options:
A. 10 feet
B. 11.25 feet
C. 12.5 feet
D. 13.35 feet
E. 14.2 feet
The closest option to our calculated value of approximately 12.5 feet is **C. 12.5 feet**.
