Respuesta :

π = C / 10    ( the is 10 because  diameter = 2 * radius)

Answer: Ratio of circumference of a circle to its diameter is 22:7.

Step-by-step explanation:

Since we have given that

Radius of circle = 5

Diameter of circle = 10

As we know the formula for "Circumference of circle":

Circumference of circle is given by

[tex]2\pi r[/tex]

Hence, ratio of circumference of circle to its diameter is given by

[tex]Circumference:Diameter\\\\2\pi r:2r\\\\\pi:1\\\\22:7[/tex]
