PLEASE HELP!!!
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?
A)
C/10 = π
B)
C/20 = π
C)
C = 10π/r
Eliminate
D) C = r/20π

Respuesta :

The correct answer is letter B because the pi represents how times the diameter it takes to make the circumference (the distance around the circle).

The diameter is double (x2) the radius, so 20 is the diameter.

If you divide the circumference by the diameter, you would get pi.

Choice B shows the correct relationship!
