Answer 1

Answer:

34.54

Step-by-step explanation:

So lets go over this.

In a circle, the line that goes straight through the middle of the circle and touches both sides is called the diameter, or d.

The radius is r, which is half the diameter, and on a circle, goes from the very middle of the circle to the side of the circle.

C is the circumference of the circle.

The formula for the circumference, C is $\pi *2r$, or $\pi *d$.

In our situation here, d is equal to 11 inches.

So if we plug that in we get:
$\pi * 11 = 34.54$

So 34.54 = c, our circumference.

Hope this helps! I can go over this further if this still confuses you too :3
