Question

Знаю длину окружности,как вычислить диаметр?

Answer 1

С=2*pi*r. r=d/2, подставим:С=2*pi*d/2. C=pi*d =>d=C/pi

Answer 2

Calculating the Diameter from the Circumference

To calculate the diameter (D) of a circle when the circumference (C) is known, you can use the formula:

D = C / π

Where: - D = Diameter - C = Circumference - π (pi) is approximately 3.14

Let's use the given information to calculate the diameter.

Given: Circumference (C) = 27.5

Using the formula: D = C / π

Substituting the values: D = 27.5 / 3.14 D ≈ 8.76

So, the diameter of the circle is approximately 8.76.
