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.?

Answer 1

The approximate circumference of a circle can be found by multiplying 3.14 by the diameter.

Given that the diameter is 1/2 inch, we can calculate the approximate circumference as follows:

Circumference = pi x Diameter
Circumference = 3.14 x (1/2)
Circumference = 3.14/2
Circumference ≈ 1.57 inches

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