If the cirumference of a circle is 16 pi what is the radius

If 16 is the diameter, then the radius is half of 16.

87

To find the radius of a circle when the circumference is given, we can use the formula:

Circumference = 2 * π * radius

Given the circumference of 16π, we can equate the formula to the given value:

16π = 2 * π * radius

Simplifying the equation by canceling out π from both sides:

16 = 2 * radius

Dividing both sides by 2, we get:

radius = 16 / 2

Simplifying this further:

radius = 8

Therefore, the radius of the circle is 8 units.
