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 12 in. ?
The approximate circumference in inches can be calculated as follows:
Circumference = pi x diameter
Approximating pi as 3.14, and the diameter as 12 inches:
Circumference = 3.14 x 12
Circumference = 37.68 inches
Therefore, the approximate circumference in inches of a circle with a diameter of 12 inches is 37.68 inches.
