The term circular mil is common in expressing the cross sectional area of a wire. Electrical wires have very minute diameters that are often measured a thousandth of an inch. Hence, when you find the area of the circular wire, for convenience, the unit used is circular mil which is equivalent to one-thousandth of an inch.
For example, a wire has a diameter of 6×10⁻⁵ inches. To find its area:
A = πr² = π( 6×10⁻⁵ /2)² = 2.83×10⁻⁹ in²
Since 1 mil = 1/1000 (inch) or 0.001 inch
A = (2.83×10⁻⁹ in²)* (1 mil/ 0.001 inch)²
A = 0.00283 circular mils

Step-by-step explanation:
1. Two angles that sum to 90° are <em>complementary</em>, whether they are adjacent or not. Angles LMN and NMP are also <em>adjacent</em>.
2. Vertical angles created by two distinct lines are <em>never adjacent</em>. The sides of the angles are created by the same lines, and the angles share a vertex, but there is no ray that is a side common to both angles.
3. Angle GMK is supplementary to angle JMG.
4. Vertical angles are congruent. See question 2.
5. See question 1.
Answer:
The three numbers are 119, 238 and 357
Step-by-step explanation:
Let's call "a number":
n
It's double is then:
2
n
And, it's triple is:
3
n
The sum of these three numbers is 714 so we can write:
n
+
2
n

3
n
=
714
We can solve as follows:
