which lets us find the circumference C C of any circle as long as we know the diameter d d. Using the formula C = \pi d C = π d Let's find the circumference of the following circle: 10 10 The diameter is 10 10, so we can plug d = 10 d = 10 into the formula C = \pi d C = πd: C = \pi d C = πd C = \pi \cdot 10 C = π ⋅ 10 C = 10\pi C = 10π That's it!
