Question

The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of 1/2 in.
?

Answer 1

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

\[ \text{Circumference} = \pi \times \text{Diameter} \]

Given that the diameter is \( \frac{1}{2} \) inch and using \( \pi \approx 3.14 \), you can calculate the circumference as follows:

\[ \text{Circumference} \approx 3.14 \times \frac{1}{2} \]

Calculating that:

\[ \text{Circumference} \approx 3.14 \times 0.5 = 1.57 \text{ inches} \]

Therefore, the approximate circumference of the circle is 1.57 inches.
