The diameter of the circle is given as 1/2 inch. Using the formula for the circumference of a circle, which is π times the diameter, we can substitute the value of π as approximately 3.14:
Circumference = π * diameter
Circumference = 3.14 * (1/2)
Circumference = 3.14/2
Circumference ≈ 1.57 inches
This circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, it is what is the approximate circumference in inches of a circle with a diameter of 1/2 in?
