Step-by-step explanation:

Step-by-step explanation:

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.

Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.

The radius is half of the diameter. So for number 8, the answer would be 2.

hope this helps and that it wasn't to confusing  :)
