Answer:
6
Step-by-step explanation:
The radius of a circle does not change with direction, it stays constant. This, the radius of the bigger circle is 4, and of the smaller circle is 2. Thus, OP equals 4 + 2 = 6. You're correct! :)
it is 6 because when yo look at the pie it says 4 and 2 so add them it's 6
