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.? (1 point)
The approximate circumference of a circle with a diameter of 1/2 inch is calculated as:
Circumference = pi * diameter
Approximate circumference = 3.14 * (1/2)
Approximate circumference = 1.57 inches

To find the approximate circumference of a circle with a diameter of 1/2 inch, we can use the formula: Circumference = pi * diameter.
Given that the diameter is 1/2 inch, we substitute this value into the formula:
Circumference = 3.14 * (1/2)
Multiplying the values, we get:
Circumference = 3.14 * 1/2 = 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 circumference of a circle with a given diameter, you can use the formula: C = π * d, where C represents the circumference and d is the diameter.
In this case, the diameter is given as 1/2 inch. To calculate the circumference, we need to substitute the value of the diameter into the formula using an approximate value for pi (3.14).
So, using the given diameter of 1/2 inch and approximating pi as 3.14, we can calculate the circumference as follows:
C = 3.14 * (1/2)
= 3.14/2
= 1.57
Hence, the approximate circumference of the circle with a diameter of 1/2 inch using an approximation for pi as 3.14 is approximately 1.57 inches.
