WebJan 30, 2024 · Since the diameter extends all the way across the circle, the diameter is equal to two radii. A simple way to write this is d = 2r. This means you can always replace a d with a 2r in a math problem, or the other way around. We'll be using d, not 2r, since your math problem tells you what d equals. trulicity vs saxenda weight lossWebThe 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).
