Circumference of a circle in inches

WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. Web**These two formulas are just two different ways of finding the same thing (circumference) because the diameter of a circle $$ =2 \cdot radius $$. So you can use whichever formula is more convenient. If you know a circle's radius, use the formula with radius ($$ 2 \cdot \pi \cdot radius $$) ; if you know the diameter, use the ($$ \pi \cdot ...
