1) The length of the circle C is equal to 2 times the constant number “pi” and the radius of the circle (r). Let’s round pi to 3.14.

Thus, C = 2Pr = 2 * 3.14 * 1.25m = 7.85m.

2) Let us express the diameter in terms of the circumference:

d (diameter) = C (circumference): Pi

Let’s round pi to 3.

Then d = 135cm: 3 = 45cm.
