Consider circles 7 through 12. If circle 7 is at 45°, what is the radian measure of each of these circles in relation to the main circle? Explain how you know these values.

Hello your question lacks vital information attached below is the vital information

Along with the image below, Use your knowledge of the unit circle and radian measure of angles to answer the following questions. [Note: When the questions ask you to consider circles and their angle in relation to the main circle, the question is referring to the location of the center of each circle.]

Circle 7 = π / 4

Circle 8 = 7π / 12

Circle 9 = 11 π / 12

Circle 10 = 5π / 4

Circle 11 = 19π / 12

Circle 12 = 23π / 12

Step-by-step explanation:

Given that 45° = π/4.

∴  All the six(6) circles ( 7 through 12 ) are separated by : 60° = π/3

The Radian measure of the remaining circles through 12 :

Circle 8 = π/3 + π /4 = 7π / 12

Circle 9 = π/4 + 2 π/3 = 11 π / 12

Circle 10 = 5π / 4

Circle 11 = 19π / 12

Circle 12 = 23π / 12

Reason : All the six(6) circles ( 7 through 12 ) are separated by : 60° = π/3

i believe the correct answer is b.
