The diameter of a circle is 163 ft. Find the circumference to the nearest whole number.
Answer

To find the circumference of a circle, you can use the formula:

\[
C = \pi \times d
\]

where \( C \) is the circumference, \( \pi \approx 3.1416 \), and \( d \) is the diameter.

Given:
- Diameter \( d = 163 \, \text{ft} \)

Now, calculate the circumference:

\[
C = 3.1416 \times 163 = 512.085 ft
\]

Rounding to the nearest whole number:

\[
C \approx 512 \, \text{ft}
\]

So, the circumference is **512 feet**.
