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 ½ in.? (1 point)

Question

in.

Answer 1

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

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

Given the diameter of the circle is \( \frac{1}{2} \) inches and using \( \pi \) as approximately \( 3.14 \):

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

Calculating this gives:

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

So, the approximate circumference of the circle is \( 1.57 \) inches.
