WebCircumference = d×pi or 2r×pi. So if the circumference is 34pi we could divide that by pi and omit the pi (using the circumference equation) and we are left by the diameter and … WebJun 15, 2024 · Given: the formula for the circumference of a circle is C = 2r, where r is the radius and C is the circumference. The circumference of a circle is equal to π. π ≈ 3.14 . multiplied by the diameter of the circle. Therefore, the diameter has twice the length of the radius. In equation form: 2r = d. 2r = 16. r = 8. Note, 2r = d, Then, the ...
