Answer:
B 12 pi m^2
Step-by-step explanation:
The area of the circle is pi r^2
We know the radius is 6
A = pi (6)^2 = 36 pi
The sector is 120 degrees. The entire circle is 360 degrees.
The fraction is 120/360 = 1/3
The sector covers 1/3 of the circle so it is 1/3 of the area
1/3 A = 1/3 (36 pi) = 12 pi
Answer:

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:
6.65
Step-by-step explanation:
7- 0.35 = 7.00- 0.35 = 6.65
The expression for the circumference of the circle is 2πr, where π is approximately 3.14 and the r is the radius of the circle, 1.4 inches. So the circumference of the circle is
. So the circumference of the circle is 8.792 inches.
