Final answer:
The circumference of a circle with a radius of 4 units can be calculated using the formula C = 2πr, which equals approximately 25.13 units when using π as 3.14159.
Explanation:
To determine the circumference of a circle with a radius of 4 units, we need to use the circumference formula:
C = 2πr
Where C represents the circumference, π (pi) is approximately 3.14159, and r is the radius of the circle.
π is a special mathematical constant that represents the ratio of the circumference of any circle to its diameter, and for most practical calculations, it can be approximated as 3.14. Therefore, plugging the radius (4 units) into the formula we get:
C = 2 x 3.14159 x 4
C = 8 x 3.14159
C = 25.13272 units
We can round this answer to two decimal places for simplicity, obtaining:
C = 25.13 units
So, the circumference of a circle with a radius of 4 units is approximately 25.13 units.
The circumference of a circle with a radius of 4 units is approximately 25.12 units.
Explanation:The circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius. In this case, the radius is given as 4 units, so we can substitute that value into the formula to find the circumference.
C = 2π(4) = 8π units.
Since π is approximately 3.14, we can approximate the circumference as:
C ≈ 8 x 3.14 = 25.12 units.
Therefore, the circumference of the circle with a radius of 4 units is approximately 25.12 units.

If you flip two coins 12 times, what is the best prediction possible for the number of times both coins will land on tails?
_____ times
Answer:
3
Step-by-step explanation:
I know I'm late by 4 years but the answer is 3. This is because if you divide 12 by the 2 coins you'll get 6. You then need to divide it in half again because it's asking for both coins not only one. This gets you the answer of 3. I'm only writing this because other people may need help, 4 years later-

a refrigerator is 3 ft wide,2.5 ft deep,and 6 ft high.the walls and other parts of the refrigerator take up 20ft.how many cubic feet are left for food?
To calculate the available space for food in the refrigerator, multiply its external dimensions (3 ft wide, 2.5 ft deep, and 6 ft high) to get the total volume of 45 cubic feet. Subtracting the 20 cubic feet taken up by the walls and other parts, we find there are 25 cubic feet left for food storage.
Explanation:The question asks us to calculate the available space for food inside a refrigerator given its external dimensions and the space taken up by the walls and other parts. The refrigerator is 3 ft wide, 2.5 ft deep, and 6 ft high. The total internal volume before accounting for walls and other parts is calculated by multiplying these dimensions:
Volume = Width × Depth × Height = 3 ft × 2.5 ft × 6 ft = 45 cubic feet.
Given that the walls and parts take up 20 cubic feet, we subtract this from the total internal volume to calculate the space left for food:
Available space for food = Total internal volume - Space taken by walls and parts = 45 cubic feet - 20 cubic feet = 25 cubic feet.
Therefore, the refrigerator has 25 cubic feet of space available for storing food.

The two-way table shows the results of a survey about high school students' music preferences. Which graph correctly displays the relative frequencies of the three types of music shown in the two-way table?
We are given a two-way table that represents the frequency of three types of music.
Hence, the relative frequency table is given by:
Female Male Total
Country 145/1015 106/1015 251/1015
Rap 158/1015 240/1015 398/1015
Rock 214/1015 152/1015 366/1015
Total 517/1015 498/1015 1015/1015
Female Male Total
Country 0.143 0.104 0.247
Rap 0.155 0.237 0.392
Rock 0.211 0.150 0.361
Total 0.509 0.491 1
Hence, clearly we could see that the relative frequency of the music country is much low as compared to that of Rock and rap.
Hence, there is a much difference between the bar of Country as compared to Rock and rap.
and there is a low difference between the bar of rock and rap.

What measurements of a cone can be found if you know the volume and height? Explain how to apply the formula.
Answer:
The base area , radius, and diameter can be determined when given the volume and height of a cone. Substitute the values for the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable. To find the diameter, double the radius.
Step-by-step explanation:
The formula for the cone is [tex]\frac{1}{3} \pi r^2 h[/tex]. The cone is a three-dimensional geometric object with a circular base that tapers to a point called the vertex from a flat base.
What is a cone?It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
The volume of a cone is;
[tex]\rm V = \frac{1}{3} \pi r^2 h[/tex]
Where
h is the height of the cone
r is the radius
V is the volume
Hence the formula for the cone is [tex]\frac{1}{3} \pi r^2 h[/tex]

Problem The sum of 3 consecutive odd numbers is 51. What is the second number in this sequence?
Answer: 42
Step-by-step explanation:
Call the first number in the sequence xx.
Hint #22 / 8
The next even number in the sequence is x + 2x+2
Hint #33 / 8
The sum of the 66 consecutive even numbers is:
x+ (x + 2)+ (x + 4)+ (x + 6)+ (x + 8)+ (x + 10) = 270x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=270
Hint #44 / 8
6x + 30= 2706x+30=270
Hint #55 / 8
6x = 2406x=240
Hint #66 / 8
x = 40x=40
Hint #77 / 8
Since xx is the first number, x + 2x+2 is the second even number.
Hint #88 / 8
Thus, the second number in the sequence is 4242.

Suppose a small airplane has a wingspan of 15 feet. Find the wingspan of a model of the airplane, in inches, if the scale factor is 1 60 .
Solution:
we are given that
Airplane has a wingspan of 15 feet.
we have been asked to find the wingspan of a model of the airplane, in inches, if the scale factor is 1:60 .
It mean for each one unit of original wingspan we are supposed to have [tex]\frac{1}{60}th[/tex] times the wingspan of model airplane.
Here the original airplane has a wingspan of 15 feet. So the model airplane has a wingspan of [tex]\frac{1}{60}*15=\frac{1}{4} ft[/tex]
Since one fit=12 inches So we can say
[tex] \frac{1}{4} ft=\frac{12}{4} inches=3 inches.[/tex]
Hence the model airplane has a wingspan of 3 inches.

how to unfoil quickly try not to use a lot of steps.
Final answer:
To unfoil quickly, use the reverse foil method. Identify the first and last terms of each binomial, multiply them, and rewrite the middle term as the sum of the products. Example: (x + 2)(x - 3) = x^2 + 2x - 3x - 6.
Explanation:
To unfoil quickly, you can use a shortcut called the reverse foil method. Reverse foil allows you to quickly determine the original factors of a quadratic expression that has been expanded using the distributive property. Let's say we have the expression (x + 2)(x - 3) and we want to unfoil it. Start by identifying the first term of each binomial, which in this case is x from (x + 2) and x from (x - 3). Multiply these two terms together to get x^2. Then, identify the last term of each binomial, which is 2 from (x + 2) and -3 from (x - 3). Multiply these two terms together to get -6. Finally, rewrite the middle term of the expanded expression as the sum of the two products obtained: (x^2 + 2x - 3x - 6). In this way, you can unfoil the expression quickly and identify the original factors without having to expand it fully.
