Question 4:  The minor arc is AB and has a measure of 115°.

Question 5:

Question 6: The area of the figure is

Question 7:

Question 8:

Step-by-step explanation:

Question 4:

The minor arc of the circle that subtends the least degrees, and for this circle it is AB and has a measure of 115°.

Question 5:

The length of the arc of the circle with a radius subtending radians is

The arc YPX measures 360° - 90° = 270, which is ; therefore,

Question 6:

We first need to find what percent of the circle the figure is.

165° is

percent of 360°.

Therefore, the area of the figure must also be 45.83% of the area of the circle. The area of the circle is  

therefore, the are of the figure is

Question 7:

One radian is 57.296°; therefore, -340° in radians is

Question 8:

One radian is 57.296°; therefore, radians in degrees is
