The unit Circle is a platform for describling all the possible angle measures from 360 degrees all negative of those angles plus all the multiplies of the positive and negative angles from negative infinity to postive infinity hope this helps you
Answer:
sin(4π/21)
Step-by-step explanation:
Step 1: Rearrange expression
sin(π/3)cos(π/7) - cos(π/3)sin(π/7)
Step 2: Use sin(A ± B)
sin(π/3 - π/7)
Step 3: Evaluate
sin(4π/21)
And we have our answer!
By definition, the area of a circle is given by:

Where,
r: radius of the circle.
Substituting the values in the given expression, we have:

Rounding to the nearest tenth we have:
Answer:
Approximately needed:
30, 34
You add 4 on
44
Because it starts at 10 and 10 cannot be divided by 4
