The circle with center C was used as a model for a hot tub. The length of is 2 m. What is the circumference of the hot tub?

You don't say what the "length of" is the length of

If the radius is 2m, then the circumference is
2πr = 4π m

To find the circumference of the hot tub, we need to find the circumference of the circle with center C.

The circumference of a circle can be found using the formula:

Circumference = 2 * π * radius

Given that the length of the radius is 2 m, we can substitute this value into the formula:

Circumference = 2 * π * 2

Simplifying the expression:

Circumference = 4π m

Therefore, the circumference of the hot tub is 4π meters.
