Answer:
4 inches
Step-by-step explanation:
The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius.
We want to find the diameter. The diameter is twice the radius, or
d=2r
We know the radius is 2, so we can substitute that in for r
d=2*2
Multiply
d=4
So, the diameter is 4 inches
