A Rhombus has four equal straight sides. We can assume that the rhombus in this problem is square-shaped with 90° angles.
m1 = 18x ; 90 = 18x ; 90/18 = x ; 5 = x
m2 = x + y ; 90 = 5 + y ; 90 - 5 = y ; 85 = y
m3 = 30z ; 90 = 30z ; 90/30 = z ; 3 = z
x = 5 ; y = 85 ; z = 3
x + y + z ⇒ 5 + 85 + 3 = 93

Answer:
<h2>12.5 millimeters (mm).</h2>
Step-by-step explanation:
<u>Explain/define:</u>
<u>CIRCUMFERENCE: THE DISTANCE AROUND A CIRCLE.</u>
<u>DIAMETER: THE LENGTH OF A STRAIGHT LINE THROUGH THE CENTER OF A CIRCLE.</u>
<u>Mathematics: Formula</u>



<u>Mathematics: Solve</u>
To find the length of the diameter from the circumference, divide the circumference by pi. The quotient is the diameter.
3.14 is often used for pi.

<u>Conclude:</u>
Therefore, the length of the diameter of the circle is 12.5 millimeters (mm).
