To find the approximate circumference of a circle, you can use the formula:
Circumference = π x diameter
Given that the diameter is 1/2 inch and π is approximated as 3.14, we can substitute these values into the formula:
Circumference = 3.14 x (1/2)
To simplify the calculation, let's multiply:
Circumference ≈ 3.14 x 0.5
Circumference ≈ 1.57 inches
Therefore, the approximate circumference of a circle with a diameter of 1/2 inch is approximately 1.57 inches.
To find the approximate circumference of a circle with a given diameter, you can use the formula:
Circumference = π × Diameter
Given that the diameter is 1/2 inch and using the approximation of π as 3.14, we can substitute these values into the formula and calculate the approximate circumference:
Circumference = 3.14 × (1/2)
Circumference = 3.14 ÷ 2
Circumference ≈ 1.57 inches
Therefore, the approximate circumference of the circle with a diameter of 1/2 inch is approximately 1.57 inches.
