Answer:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
Step-by-step explanation:
The formula for arc length is:
[tex]\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})[/tex]
Where Θ is measured in degrees.
We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:
[tex]8\pi=2\pi r(\frac{80}{360})[/tex]
Divide both sides by 2π:
[tex]4=r\frac{80}{360}[/tex]
Simplify the fraction:
[tex]4=\frac{2}{9}r[/tex]
Multiply both sides by 9/2:
[tex]r=18[/tex]
So, the radius is 18.
Now, we can find the area of the circle. The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 18 into r:
[tex]A=\pi (18)^2[/tex]
Simplify:
[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]
And we're done!

In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C.
Answer:
Down Below :))
Step-by-step explanation:
This is quite simple.
Take a look at both of the numbers, see how their both 29?
Subtracting 29 - 29 = 0
Explanation: The average temperature was 0 because when subtracting 29 - 29, it gives you 0.
The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.

The product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex]. Options incorrect.
1, Converting the mixed numbers to improper fractions.
[tex]2\frac{5}{8}[/tex] can be written as [tex]\frac{2*8 + 5}{8}[/tex] = [tex]\frac{21}{8}[/tex].
[tex]- 2\frac{3}{5}[/tex] can be written as [tex]\frac{-2*5 + 3}{5}[/tex] = [tex]-\frac{7}{5}[/tex].
2, Multiplying the two fractions.
[tex]\frac{21}{8} * -\frac{7}{5}[/tex] = [tex]- \frac{147}{40}[/tex]
3. Expressing the result as a mixed number.
To express [tex]- \frac{147}{40}[/tex] as a mixed number, divide the numerator by the denominator:
-147 ÷ 40 = -3 with a remainder of -27.
So, the final answer is:
[tex]- 3 \frac{27}{40}[/tex].
Therefore, the product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex].
In this calculation, we used the concept of converting mixed numbers to improper fractions, multiplying fractions, and simplifying the resulting fraction.

Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg A. How much flour is this when rounded to the nearest tenth B. How much flour is this when rounded to the nearest tenth Explain your thinking
Answer:
2.9 kg
Step-by-step explanation:
If you round 2.915 to the nearest tenth, it would be 2.9. this is because the number to the right of the 9 (1) is below 5.
The amount of flour after rounded to the nearest tenth will be 2.91 kg.
What is rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.
Given that;
Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.
Now,
Since, Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.
We know that;
When we round to the nearest tenth we see the right digit of tenth place if it is less than 5 then write same as number but if the number is greater than 5 then add one on the tenth place number.
Hence,
The amount of flour after rounded to the nearest tenth = 2.9
Because, 1 < 5
Thus, The amount of flour after rounded to the nearest tenth = 2.9 kg
