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 the diameter of 1/2 inches?

Answer 1

The circumference of a circle is given by the formula C = πd, where C is the circumference and d is the diameter.

Given the diameter of 1/2 inches, we can substitute this value into the formula:
C ≈ 3.14 * 1/2.

Simplifying the expression, we have:
C ≈ 3.14 * 0.5.

C ≈ 1.57.

Therefore, the approximate circumference of a circle with a diameter of 1/2 inches is approximately 1.57 inches.
