Answer:
2
Step-by-step explanation:
The temperature was originally 2 degrees because if you draw a number line and put a 0 in the middle of the positive numbers and the negative numbers ( - 8 - 7 - 6 -5 - 4 0 1 2 3 4 5 6 7 8) - example. Put the positive and negative numbers on different sides of the 0 and go left from the positive numbers from 2 and count 6 skips down to - 4. So 2 would be your answer.

OK, no figure, but from the comment is sounds like the grey area is the big circle minus the small circle.
The diameter of the small circle is 2 so its radius is 1 and its area πr² is π.
The radius of the larger circle is 4, so area 16π
The shaded area is 16π - π
Answer: 15π
Answer:
108
Step-by-step explanation:
Hey There!
So the arc is equal to its corresponding angle
We are given the angle of KL which is 30 so all we need to do is find the length of arc JK
The angles given and the missing angle are supplementary angles meaning that they will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-30-72=78
Now we just add arc JK and arc Kl
30+78=108
so arc JL is equal to 108
