Considering the described changes, the temperature at 6 pm was of -14.5ºF.
<h3>How to find the temperature at 6 pm?</h3>
We look at the temperature for each interval, as follows:
- At 9 am, the temperature was -8.4°F.
- Between 9am and noon, the temperature increased by 2.6°F, hence, at noon, the temperature was of -8.4ºF + 2.6ºF = -5.8ºF.
- Between noon and 3pm, the temperature rose 1.2°F, hence, at 3 pm, the temperature was of -5.8ºF + 1.2ºF = -4.6ºF.
Between 3pm and 6pm, the temperature went down 9.9°F, hence at 6 pm, the temperature was given as follows:
-4.6ºF - 9.9ºF = -14.5ºF.
The temperature at 6 pm was of -14.5ºF.

Step-by-step explanation:</h3>
You want to choose an assignment of numbers that makes the number of numbers that represent each color be the same.
Numbers 0–33 include 34 numbers. Numbers 0–99 include 100 numbers, so blue blocks are over-represented by scenario A.
Scenario B suffers the same problem as scenario A in that 0–3 includes 4 numbers and 0–9 includes 10 numbers.
Scenario D has the opposite problem: 1–31 is 31 numbers, but 32–63 is 32 numbers. Blue blocks are under-represented in this scenario.
___
Scenario C has 3 of 9 numbers representing each color—just what you want.
Answer:
The outering is 11 cm so let's see what the Area is. We use the formula Area of a circle:
A = πr² = πd2/4
If:
Radius, r = 11 cm
Then:
Diameter, d = 22 cm
Circumference, C = 69.115038378975 cm
Area, A = 380.13271108436 cm²
now all we need to do is subtracts the inner circle Area.
If:
Radius, r = 9 cm
Then:
Diameter, d = 18 cm
Circumference, C = 56.548667764616 cm
Area, A = 254.46900494077 cm²
Thus: 380.13271108436 cm² - 254.46900494077 cm² =
125.6637061436 cm²
