WebAn ice skater rotates in a circle about an internal axis of rotation. Figure 1 shows the skater with her arms extended fully outward. Figure 2 shows the skater with her arms partially inward to her body. Figure 3 shows the skater with her arms completely inward and in contact with her body. WebThe ratio of the length (circumference) of a circle, C to its diameter m is π (a Greek letter spelled pi and pronounced "pie" in English-speaking countries). The decimal representation of π continues forever without repeating after the decimal point: π = 3.14159265... So if C / m = π, then C = m ⋅ π. Share Cite Follow answered Apr 1, 2016 at 21:58
