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
Answer: 16%
Step-by-step explanation:
The total number of species of shark evaluated = 465
Number of sharks currently endangered or threatened = 74
Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%
= (74/465) x 100%
= 0.1591 x 100%
= 15.91%
Round 15.91% to the nearest whole percent = 16%
Thus, 16% of the total sharks evaluated are currently endangered or threatened.
Hi,
The square root of √ 7 is 2,645751.
45/900=110/x
x=(110/45)*900=2200 students
