Based on the information given, which formula should we use to calculate the circumference of the circle?
C=πd
C=2πr
Answer:
Step-by-step explanation:
The two formulas are essentially the same. Recall that 2r = d (and of course d = 2r). If you're given the diameter, d, use C = πd; if you're given the radius, use C = 2πr.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

What is the approximate circumference of the circle below?
A. 25.1 centimeters
B. 28.3 centimeters
C. 31.4 centimeters
D. 34.6 centimeters
Answer:
A) 25.1 cm
Step-by-step explanation:
Circumference of a circle = \(2\pi r\), where r = radius
⇒ circumference of circle with radius 4 cm = 2 x \(\pi\) x 4 = 8\(\pi\) ≈ 25.1 cm

Answer:
d. 2x^2-8x
Step-by-step explanation:
ure just doing distributive property.
The product of 2x(x-4) is 2x² - 8x
HOW TO OPEN BRACKET?In a mathematics, algebraic expressions can be in bracket. This bracket means we multiply all the variables outside by those inside.
According to this question, we are given the following expression: 2x(x-4)
This means that 2x multiples x and -4 independently.
That is; 2x × x and 2x × -4
2x² - 8x
Therefore, the product of 2x(x-4) is 2x² - 8x.

Answer:1 to 2

Step-by-step explanation:
A circle’s circumference is 600 m.
What is a good approximation of the circle’s area? 1. 300\ m^{2} 2. 3,000\ m^{2} 3. 30,000\ m^{2} 4. 300,000\ m^{2}
The area of the circle is approximately 30,000 \(m^{2}\)
The circumference of the circle is given as 600m.
And we know that circumference = \(2\pi r\) where r is the radius of the circle.
Therefore,
\(2\pi r = 600\)
\(r = \frac{600}{2\pi }\)
\(r = \frac{300}{\pi }\)
Now, we know that area of the circle = \(\pi r^{2}\)
Putting the value of r in this, we get
area = \(\pi (\frac{300}{\pi } )^{2}\)
area = \(\pi.\frac{300}{\pi } .\frac{300}{\pi }\)
Therefore, area of the circle = 28,647.889 \(m^{2}\)
Therefore, the correct answer is 30,000 \(m^{2}\)
