on the target below the 5- and the 10- point bands are each 2 inches wide
and the 25- point inner circle has a diameter of 2 inches
the the nearest inch what is the outer circumference pf the 10- point band
~~~~~~~~~~~~~~~~~
There is no picture or a reference to diagram, so (formally) I don't know what is presented there.
But my common sense tells me that there is 25-point inner circle of the diameter of 2 inches;
then a circular 10-point band goes of 2 inches width;
then a circular 5-point band goes of 2 inches width.
The question is to find the outer circumference of the 10- point band.
The radius of this circle is r = = 1 + 2 = 3 inches.
Therefore, the circumference of this circle is
= = = 6*3.14159 = 18.850 inches (approximately).
ANSWER. The outer circumference of the 10-point band is = 18.850 inches (approximately).
Solved.

@greenestamps in his solution determined the circumference of the most outer circle, which was not the question.
