Answer:
1.92cm
Step-by-step explanation:
Circumference of a circle is computed using the formula:

Where:
r = radius
π = 3.14
Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.
We can then use the diameter to solve for the circumference by using the formula"

So we just plug in what we know in the formula:

3/4 divide by 5 is equal to 3/20
