The formula for the circumference of a circle is as follows: P = 2ПR, where P is the circumference, P is pi, equal to 3.14, and R is the radius of the circle.

Let us find the radius by this formula: R = P / 2P.

We substitute the initial data: R = 64.056 / 2 * 3.14 = 10.2 dm.

Thus, the radius of a given circle is 10.2 dm.

It is known that the diameter is twice the radius, then: 10.2 * 2 = 20.4 dm.

Thus, the diameter of a given circle is 20.4 in.
