The radius of a circle and it's circumference

Direct or inverse

If you increase the radius of a circle, does its diameter increase or does it decrease?

The area of the circle to its radius

The relationship between the radius of a circle and its circumference is direct. This means that as the radius of a circle increases, its circumference also increases, and vice versa.

The relationship between the radius of a circle and its circumference can be described as follows:

Direct:

The radius and circumference of a circle have a direct relationship, which means that as the radius of a circle increases, its circumference also increases. Conversely, as the radius decreases, the circumference decreases as well.

To calculate the circumference of a circle, you can use the formula:
Circumference = 2 * π * Radius

So, if you know the radius of a circle, you can simply multiply it by 2, π (pi), and you will obtain the circumference.

Inverse:

The relationship between the radius and circumference of a circle is not inverse. An inverse relationship implies that as one variable increases, the other decreases, and vice versa. However, this is not the case with the radius and circumference of a circle.
