Q:
The radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
Accepted Solution
A:
The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
