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 formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.
Using the approximation of π as 3.14, we can substitute the given diameter of 12 inches into the formula:
C = 3.14 * 12 = 37.68 inches.
Therefore, the approximate circumference of the circle with a diameter of 12 inches is 37.68 inches.
To find the approximate circumference of a circle with a diameter of 12 inches using the approximation of pi as 3.14, you can use the formula:
Circumference = π × Diameter
Substituting the given values:
Circumference = 3.14 × 12
Calculating:
Circumference ≈ 37.68 inches
Therefore, the approximate circumference of a circle with a diameter of 12 inches is approximately 37.68 inches.
