Answer:
[tex]\frac{circumference\ }{diameter}=\pi[/tex]
Step-by-step explanation:
Given that radius of the circle = 10
Using π, we need to find about which equation expresses the ratio of the circumference of the circle to the circle's diameter.
diameter of the circle = 2(radius) = 2(10)=20
circumference of the circle = 2 π r = 2 π (10) = 20 π
then ratio of the circumference of the circle to the circle's diameter is given by: [tex]\frac{circumference\ }{diameter}=\frac{20\pi}{20}=\pi[/tex].
Hence required equation is [tex]\frac{circumference\ }{diameter}=\pi[/tex]
