Let’s calculate the length of the second circle, whose diameter is 5/7 of the diameter of the first circle.
The diameter of the first circle is 3.5 in.
In order to find the diameter of the second circle, you need to multiply the diameter of the first circle by 5/7. That is, we get:
c = 3.5 dm * 5/7 = 7/2 * 5/7 dm = ½ * 5/1 dm = 5/2 dm = 2.5 dm;
From this it was obtained that the length of the second circle is equal to c = 2.5 dm.
