find the circumference of a circle with a radius of 9, that's what it is asking, but I don't understand it, so can you help me?​

Respuesta :

The formula for getting the circumference of a circle is [tex]C = 2\pi r[/tex] where 'r' is the radius. Just plug in the value for the radius.

[tex]C = 2\pi * 9[/tex]

We will also use 3.14 for PI.

[tex]C = 2 * 3.14 * 9[/tex]

C = 56.52

Hope this helps!
