What is the circumference of the diameter which is equal to 1 m?

The circumference (denoted as C) is calculated in mathematics by the formula C = 2 * n * R, where n is the number “pi”, its approximate value is 3.14, but the task does not ask to substitute a number instead of n, so we will not …

So, C = 2 * n * R. But in the task a diameter of 1 m is given, and the radius (R) is equal to half the diameter, i.e. 0.5m. we substitute the data into the formula:

C = 2 * n * R = 2 * n * 0.5 = 1 * n = n (m). {reads “pi” meters}
