Answer:
125.6
Step-by-step explanation:
The formula for circumference is [tex]2\pi r[/tex]. The diameter of a circle is twice the amount of the radius. Hence we can replace pi with 3.14 and r with 20 to get [tex]2(3.14)(20)[/tex]. We can simplify this and multiply these together to get [tex]125.6[/tex].
This could've been done easier with [tex]2r[/tex] actually being equal to the diameter so we could've replaced [tex]2r[/tex] with [tex]40[/tex] and solved [tex]40(3.14)[/tex].
