Answer: -3π/2
Step-by-step explanation:
The unit circle is tricky, but here are some things to know:
- When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative.
- The unit circle is typically measured in radians, not degrees
- To convert from radians to degrees, multiply by 180/π
- To convert from degrees to radians, multiply by π/180
- The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.
-If the angle is negative, switch the signs of the axis above.
The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.
Answer:263.9 in squared
Step-by-step explanation:
Find the area of the whole circle
Multiply area times the angle of the shaded region by total angle
Get answer
(pi)(12^2) = Area of whole
(Whole area)x(210deg/360deg)
=== 263.9 in squared

Answer:
8%
Step-by-step explanation:
We will use the equation provided to solve this problem.
Lets plug in the values:
First, divide both sides by 800.
Multiply x by 1
Now, we multiply .08 by 100 to get our interest rate:
(.08)100 = 8
The interest rate is 8%
