Question

The diameter of a circle is 169 in. Find the circumference to the nearest whole number.

Answer 1

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

\[
C = \pi d
\]

where \( C \) is the circumference and \( d \) is the diameter.

Given that the diameter \( d \) is 169 inches, we can substitute that value into the formula:

\[
C = \pi \times 169
\]

Using the approximate value of \( \pi \) as 3.14, we can calculate:

\[
C \approx 3.14 \times 169 \approx 530.86
\]

Now, rounding this to the nearest whole number gives:

\[
C \approx 531
\]

Thus, the circumference of the circle is approximately **531 inches**.
