Answer:
10π
Step-by-step explanation:
RULE: The angle measure of the central angle is congruent to the measure of the intercepted arc.
RULE: Central Angle = Arc length
Given:
Arc length (20 π) = central angle (180)
we know 180 degrees is a straight line, thus a semi-circle is created. This would be the diameter.
1/2 diameter is the radius. 20π/2 is the radius.
10π
What do you want me to find

To convert into decimal, move the decimal to the left by 6 positions.
It will be 0.00000563
Answer is A.

is a fraction with the denominator 6. It is less than one (5/6 = 0.83 [rounded]. 0.83 is less than 1) but greater than

(3/4 = 0.75. 0.75 is less than 0.83)
Note: To turn a fraction into a decimal you simply divide the numerator by denominator. (
→ numerator/denominator → (decimal)
I believe it should be 4. Because a trend line should be a line that shows the trend haha so it should be equal. Not sure if that makes sense sorry if I didnt explain it well.
