The area of a circle is a= 2 pi r ... so just Take half of that pi (radius) ... and the radius is 3 because 6 is the length across the circle ot the diameter and the diameter is 2 times the radius... your answer is 3.14 (3) = 9.42
Neck: In 2/3 of an hour Naomi will stretch her neck one (there's not enough time for two neck stretches, that would require an hour).
Legs: In 2/3 of an hour, she will stretch her legs twice (1 stretch every 1/3 of an hour for 2/3 of an hour equals 2).
Arms: In 2/3 of an hour she will stretch her arm four times (2/3 divided by 1/6 equals 4).
Total stretches: 1 neck stretch, 2 legs stretches, and 4 arms stretches.

Answer:
x = 10°, y = 20°
Step-by-step explanation:
Fill in the missing angle measures, 20° and 70°.
7x = 180 - 90 - 20
7x = 70
x = 10
2y = 180 - 7x - 5x - 20 = 40
y = 20
