Consider the following two circles.
Segment d1 is a diameter of ⨀A, and segment d2 is a diameter of ⨀B.

If d1=1 and d2=2r, and if CB denotes the circumference of ⨀B, which equation is true?
1/2r = CB/2π
1/2r = π/CB
1/2r = CB/π

Consider the following two circles Segment d1 is a diameter of A and segment d2 is a diameter of B If d11 and d22r and if CB denotes the circumference of B whic class=
