Webc = 2 πr or c = πd This depends on whether or not you know the radius ( r) or the diameter ( d) Let’s calculate one manually, for example. If r = 6 cm, the the circumference is c = 2 π (6) = 12 π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm. Suppose you only know the diameter? WebFeb 2, 2024 · To find the radius whose circumference is equal to 6 feet, we follow the steps below: Write the circumference as c = 6 ft. Recall the formula for the radius of a circle from circumference: r = c / (2 * π). Inject the circumference into the equation: r = (6 ft) / (2 * π) = 3/π ft. If needed, substitute π ≈ 3.14: r = 3/π ft ≈ 0.96 ft.

How to Calculate Circumference from Diameter.

WebFor example, the circumference of a circle with a radius of 4 inches is simply 2 x 3.14159 x 4 = 25.13 inches. If the diameter is given instead, first divide it by two, then repeat the above process. For example, if the … WebFeb 17, 2016 · In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units C = 2 π r = 2 π × 5 = 10 π units Q Why is circumference 2 π r? A WebJan 26, 2024 · Find diameter from circumference That same equation, C = πd, can also be used to find the diameter of a circle if you know circumference. Just divide both sides … hcpcs aranesp
