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.
