WebJul 3, 2024 · Pi is the fixed ratio used to calculate the circumference of the circle You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd WebAlso, since an angle in radians is defined as the ratio of two lengths, L/r, it is dimensionless. Since 90° = π / 2 radians, to four significant figures, one radian equals 180°/ π = 57.30°. There are 2π radians in a full circle. (So 2π radians should equal 360°. Check it out by multiplying 57.30° by 2π = 6.283.
