Which is the ratio of the circumference of any circle to the radius of the circle?
A. π
B. 2π
C. π/2
D. 2/π
I don't know this one lol
Well, what is the formula for the circumference?
D?
I'm not quite sure for this one.
C = pi * 2r
Which describes the collection of all points in the same plane that are
8 1/2 inches from Point T?
No problem! I can help you understand how to find the ratio of the circumference of a circle to its radius.
The formula to find the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius of the circle.
To find the ratio of the circumference to the radius, we can simply divide the circumference by the radius:
C/r = (2πr)/r = 2π
So the ratio of the circumference of any circle to its radius is 2π.
Therefore, the correct answer is B. 2π.
