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.? (1 point)

Question

____ in.

Answer 1

To find the approximate circumference of a circle using the formula:

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

Given that the diameter is \( \frac{1}{2} \) in and using \( \pi \approx 3.14 \):

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

Now, let's calculate this:

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

Thus, the approximate circumference of the circle is:

\[ \boxed{1.57} \text{ in.} \]
