The Circumference of a Circle with Diameter 14 cm

To find the circumference of a circle, we need to know either the radius or the diameter of the circle. In this case, we are given the diameter of the circle as 14 cm. The circumference is the distance around the circle, and it can be calculated using the formula:

Circumference = π × diameter

Where π (pi) is a mathematical constant approximately equal to 3.14159.

Step 1: Determine the Diameter
The given diameter of the circle is 14 cm. The diameter is a straight line passing through the center of the circle, dividing it into two equal halves.

Step 2: Calculate the Circumference
Using the formula for the circumference of a circle, we can substitute the given diameter into the formula:

Circumference = π × diameter
Circumference = 3.14159 × 14 cm

Step 3: Evaluate the Circumference
Now, we can calculate the circumference using a calculator or by multiplying the values:

Circumference ≈ 43.982 cm

Therefore, the circumference of a circle with a diameter of 14 cm is approximately 43.982 cm.
