A standard archery target is marked with how many evenly spaced concentric rings?
Target archery those of the same ability. The Grand National Archery Society runs two systems of classification: the main Classifications (for indoor and outdoor shooting) and Handicaps. To do this, they produce tables of scores for all recognised rounds and an archer's classification and handicap can be worked out from their scores, normally by a club's "Record Officer". For indoor rounds, an archer has a classification represented by a letter from A to H, with A being the best and H the worst. This applies for both seniors and juniors. Standard WA targets are marked with 10 evenly spaced concentric rings, which
Concentric objects pencil of circles, may be transformed into a set of concentric circles by a Möbius transformation. The ripples formed by dropping a small object into still water naturally form an expanding system of concentric circles. Evenly spaced circles on the targets used in target archery or similar sports provide another familiar example of concentric circles. Coaxial cable is a type of electrical cable in which the combined neutral and earth core completely surrounds the live core(s) in system of concentric cylindrical shells. Johannes Kepler's "Mysterium Cosmographicum" envisioned a cosmological system formed by concentric regular polyhedra and spheres. Concentric circles are
