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. ?
Using the formula for the circumference of a circle, we have:
Circumference = π × diameter
Substituting π with the approximation 3.14 and the given diameter of 12 inches, we have:
Circumference = 3.14 × 12
Calculating the expression, we find:
Circumference ≈ 37.68 inches
Therefore, the approximate circumference of a circle with a diameter of 12 inches is 37.68 inches.

I apologize for the confusion. I made a mistake in my previous response.
The square root of 9/4 is exactly equal to 3/2, not approximately equal to the square root of 2.
Thank you for pointing that out.
