What is the circumstance of a circle with a diameter of 4 feet.

Answer 1

The circumference of a circle can be calculated using the formula:

\[ C = \pi \times d \]

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

In this case, the diameter \(d\) is 4 feet. So, we can substitute the value into the formula:

\[ C = \pi \times 4 \text{ feet} \]

Using an approximate value of \(\pi \approx 3.14\), we can calculate:

\[ C \approx 3.14 \times 4 \text{ feet} \approx 12.56 \text{ feet} \]

So, the circumference of the circle is approximately 12.56 feet.
