網頁d = 2r. diameter = 2 × radius. We can actually rewrite the circumference equation using radius instead of diameter: c = πd = π(2r) Mathematicians usually write it like this: c = 2πr. The formula for circumference of a circle is 2πr. Let's use this formula to find the circumference of the circle below. c = 2πr. 網頁You use these distances to calculate the circumference, as the formula for working out the circumference is: circumference of circle = π × diameter of circle. π is equal to roughly 3.14 (also known as pi). So this equation can be shortened to: c = πd. Because of what we learned earlier about diameter and radius, you can use this formula to ...
