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)

Answer 1

The circumference of a circle is equal to pi times the diameter.
Using the approximation of pi as 3.14, we can calculate the circumference as:
Circumference = pi * diameter
Circumference ≈ 3.14 * 1/2 in
Circumference ≈ 3.14/2 in
Circumference ≈ 1.57 in

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