Answer:
50.24 cm
Step-by-step explanation:
For the easier computation of a circle's circumference, pi's value is taken to be 3.14 (π = 3.14). Let's see a few examples below to polish the concept of the circumference. Find the circumference of the circle with a radius of 8 cm. = 50.24 cm.
Answer:
Hello! answer: 50.24
Step-by-step explanation:
To find circumference you just have to do diameter × pi Since we arent given the diameter we have to figure it out BUT REMEMEBER diameter is just twice the radius so 8 × 2 = 16 so 16 is our diameter! Now we just multiply that by pi so 16 × 3.14 = 50.24 So 50.24 is the circumference! Hope this helps!

Answer:
13.85
Step-by-step explanation:
You square 16 and get 256. Then you square 8 ang get 64. then you subtract 64 from 256. You get 192, you square root that and get 13.85.
What is 767,000 expresses in scientific notation
Answer:
767,000 in scientific notation is [tex]7.67*10^5[/tex].
Step-by-step explanation:
A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 and multiplied by a power of 10. In this case, if 767,000 were to be written in scientific notation, then you need to move the decimal place of the number until you have a number that meets the requirement above. 7.67 would be the number to use, and you need to multiply that by a power of 10 that makes the product the original number, so the power would be 5. So 767,000 in scientific notation would be [tex]7.67*10^5[/tex].

how can 20% = 1/5 find 20% of 50
Please help asap
Step-by-step explanation:
Hi,
Think about it this way.
20%
40%
60%
80%
100%
We had to add 20% 5 times in order to get 100%.
The same goes for the fraction.
1/5
2/5
3/5
4/5
5/5
We had to add 1/5 5 times to get it to 5/5.
So...
20% is the same thing as... 20/100 and simplified, it's the exact same thing as 1/5.
They're basically the same exact thing except they're written in different ways.
I hope this helps, I didn't really understand what you needed exactly, but if you need anything else, feel free to let me know :)
Have a wonderful day.

convert 3600 seconds to minutes
Answer:
60 minutes
Step-by-step explanation:
60 second a minute
3600/60 = 60
Answer:
60 minutes
OR
1 hour
Step-by-step explanation:
To convert the number of seconds to minutes, the formula is:
Seconds/60 = minutes
So, let's plug in the values...
3600/60 = m
Then, we just solve.
3600/60 = 60 minutes (or one hour)
Therefore, 3600 seconds is equal to 60 minutes. (Or an hour). Hope this helps!

Answer:
1) x = 4
2) ? = 20
8) x = 5
Step-by-step explanation:
Use the applicable relationships to write an equation involving the unknown. Solve the equation.
__
1) We note that the marked arcs are the same length. In a circle, chords that subtend arcs of the same measure are the same length.
5x -1 = 4x +3
x = 4 . . . . . . . . . . add 1-4x to both sides
__
2) A tangent meets a radius at right angles. The given triangle is a right triangle, so the Pythagorean theorem applies.
12² +16² = x²
144 +256 = x² = 400
x = √400 = 20
The missing value is 20.
__
8. Tangents from the same point are the same length.
4x -8 = 12
4x = 20 . . . . . add 8
x = 5 . . . . . . . divide by 4
_____
Additional comment
In problem 2, you note the ratio of side lengths is 12 : 16 = 3 : 4. This should give you a clue that this is a 3-4-5 right triangle. The long (missing) side will be 5, scaled by the scale factor of 4, so will be 4×5 = 20.

Point P divides the directed segment from A to B in the ratio 9 to 2. The coordinates of point A are
(-4,-2) and the coordinates of point P are (2, 1). Find the coordinates of point B. Round your answer to
the nearest tenth if necessary.
Answer:
[tex]B =(3.3,1.7)[/tex]
Step-by-step explanation:
Given
[tex]A(x_1,y_1) = (-4,-2)[/tex]
[tex]P(x,y) = (2,1)[/tex]
[tex]m : n = 9 : 2[/tex]
Required
The coordinates of [tex]B(x_2,y_2)[/tex]
The line segment from ratio is calculated as:
[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
Substitute: A, P, m and n
[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]
[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]
Multiply through by 11
[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]
By comparison:
[tex]9x_2 - 8 = 22[/tex]
[tex]9y_2 - 4 = 11[/tex]
So, we have:
[tex]9x_2 - 8 = 22[/tex]
[tex]9x_2 = 22 +8[/tex]
[tex]9x_2 = 30[/tex]
Solve for x2
[tex]x_2 = 30/9[/tex]
[tex]x_2 = 3.3[/tex]
[tex]9y_2 - 4 = 11[/tex]
[tex]9y_2 = 11+4[/tex]
[tex]9y_2 = 15[/tex]
Solve for y2
[tex]y_2 =15/9[/tex]
[tex]y_2 =1.7[/tex]
So, the coordinates of B is:
[tex]B =(3.3,1.7)[/tex]
