Answer:
D. 28.54
Step-by-step explanation:
To find the area of the shaded region, find the area of the circle and divide it in 4. This will the area of the portion with the triangle.
Now, find the area of the triangle and subtract the two. The resulting value will be the area of the shaded region.
Circle:

Divide by 4 for the area of the section with the triangle.
314/4 = 78.5
Triangle:

Subtract the two, 78.5 - 50 = 28.5.
A is the greatest number and C is the least number.
Answer:
4.5
Step-by-step explanation:
Answer:
idk how to do that try to slove it
but I didn't get right answer
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
