What's the Relationship Between Diameter and Circumference of a Circle? - starpoint
What is the value of π (pi) in the formula?
How it Works
This is incorrect. The circumference of a circle is directly proportional to its diameter, but they are not equal.
Yes, you can use the formula C = πd to find the diameter when you know the circumference. To do this, rearrange the formula to solve for d: d = C / π.

So, what exactly is the relationship between the diameter and circumference of a circle? In simple terms, the diameter is the distance across the circle, passing through its center, while the circumference is the distance around the circle. To find the circumference of a circle, you need to know its diameter or radius. The relationship between the two is given by the formula: C = πd, where C is the circumference and d is the diameter. This formula demonstrates that the circumference of a circle is directly proportional to its diameter.
To find the circumference of a circle when you know the diameter, use the formula: C = πd. For example, if the diameter is 14 inches, the circumference would be approximately 43.98 inches (π × 14).
The value of π is approximately 3.14159, but it can be rounded to 3.14 for simplicity.
This is not entirely true. You can use the diameter or the circumference to calculate the radius, and vice versa.
