O Find the perimeter of the following shape, given its curves are made from parts of circles.
Give your answers in terms of π.
4cm
4cm
4cm
The diagram is not drawn to scale.
Answer:
12pi cm
Step-by-step explanation:
The Perimeter of the full shape is the sum of the lengths of the edges of the parts. For convenience in referencing them, we'll call the large curve "[tex]curve_{big}[/tex]" and the three smaller curves "[tex]curve_1[/tex]" "[tex]curve_2[/tex]" "[tex]curve_3[/tex]" in order from left to right.
Thus, the Perimeter of the full shape can be written as an equation:
[tex]P_{overall} = Length(curve_{big})+Length(curve_1)+Length(curve_2)+Length(curve_3)[/tex]Since all of those edge lengths are curves, and the question states that all of the curves are made from parts of circles, then we need to know how to find the length of the edge of a circle.
Parts of a circle
Since values in the diagram are diameters, use the formula for the Perimeter of a circle [tex]P=\pi d[/tex] (where d is the diameter).
Let's call the diameters of each of our curves "[tex]d_{big}[/tex]" "[tex]d_1[/tex]" "[tex]d_2[/tex]" "[tex]d_3[/tex]", with the subscripts denoting which curve we're referring to.
Note that for each curve, the curve only represents half of a circle. So, to find the length of each curve, we'll need half of the full perimeter of each circle.
So for instance: [tex]Length(curve_{big})=\frac{1}{2} \pi d_{big}[/tex]
Substituting back into the main equation above:
[tex]P_{overall} = Length(curve_{big})+Length(curve_1)+Length(curve_2)+Length(curve_3)[/tex][tex]P_{overall}=\frac{1}{2} \pi d_{big} + \frac{1}{2} \pi d_{1} + \frac{1}{2} \pi d_{2} + \frac{1}{2} \pi d_{3}[/tex]
Note that all terms have common factors of "one-half" and "pi" in them. These can be factored out:
[tex]P_{overall}=\frac{1}{2} \pi (d_{big} + d_{1} + d_{2} +d_{3})[/tex]
The diameter for the large Curve, is the sum of the three small diameters, so [tex]d_{big}=12cm[/tex], and [tex]d_{1}=d_{2}=d_{3}=4cm[/tex]
Substituting and simplifying (in terms of pi):
[tex]P_{overall}=\frac{1}{2} \pi ( (12cm) + (4cm) + (4cm) + (4cm) )\\P_{overall}=\frac{1}{2} \pi ( 24cm)\\P_{overall}=12 \pi cm[/tex]
Additional Understanding
Interesting for this problem, since the diameters of the 3 small curves formed the diameter of the large curve [tex]d_{1} + d_{2} + d_{3} =d_{big}[/tex], one could make a different substitution into one of our formulas above:
[tex]P_{overall}=\frac{1}{2} \pi (d_{big} + d_{1} + d_{2} +d_{3})[/tex]
[tex]P_{overall}=\frac{1}{2} \pi (d_{big} + (d_{big}))[/tex]
[tex]P_{overall}=\frac{1}{2} \pi (2d_{big})[/tex]
[tex]P_{overall}=\pi d_{big}[/tex]
Notice that [tex]\pi d_{big}[/tex] is just the full perimeter of a circle with the big diameter.
So, if one imagined starting with a full circle with the big diameter, even though the bottom half of the circle was turned into a bunch of smaller half circles, since they were in a line along the diameter of the large circle, the full perimeter of the new shape didn't change.
The number of smaller circles doesn't need to be 3 either... as long as it goes the full distance across, right along the diameter.

miles
The length of C from A is 3.5 miles if AB=3.5 miles and BC is 6 miles .
Given The length of triangle ABC AB=3.5 miles , BC=6miles and AC=d
We have to find the value of d
First of all we have to draw a perpendicular from point A on side BC .
It forms two triangles ABE and AEC if E is the point where perpendicular stands on BC.
In triangle BEA
AE=[tex]\sqrt{3.5^{2} -3^{2} }[/tex]
=[tex]\sqrt{12.25-9}[/tex]
=[tex]\sqrt{3.25}[/tex]
=1.8
Now in triangle AEC
AC=[tex]\sqrt{1.8^{2} +3^{2} }[/tex]
=[tex]\sqrt{3.24+9}[/tex]
=[tex]\sqrt{12.24}[/tex]
=[tex]\sqrt{12.24}[/tex]
=3.49 MILES
By rounding off to the nearest tenth we will get 3.4 miles
Hence the value of d is 3.4 miles.

O GLH = ILM
O m KLM = 5m ILMO
O m GLI = 2m GLH
O m GLI = 1/2m GLH + 1/2m HLI
Answer:
m∠GLI = 2m∠GLH
Step-by-step explanation:
Angle GLI (red) is made of angles GLH (purple) and HLI (green).
m∠GLI = m∠GLH + m∠HLI
First option: ∠GLH ≅ ∠ILM (Angle GLH is congruent to angle ILM.)
This doesn't tell us anything about the relationship between angles GLI, GLH and HLI. So it can't be used.
Second option: m∠KLM = 5m∠ILM (Measure of angle KLM is 5 times the measure of angle ILM.)
This also cannot be used, because it doesn't include angles GLI, GLH or HLI.
Third option: m∠GLI = 2m∠GLH (Measure of angle GLI is two times the measure of angle GLH.)
Now this option is more interesting. It includes two angles of three that we are interested in.
If angle GLI is two times angle GLH, then that means that angle GLH is congruent to angle HLI!
Let's prove this with equations.
1) m∠GLI = m∠GLH + m∠HLI (from picture)
2) m∠GLI = 2m∠GLH (from third option)
Substitute m∠GLI in first equation with m∠GLI in second.
m∠GLI = m∠GLH + m∠HLI
2m∠GLH = m∠GLH + m∠HLI
m∠GLH = m∠HLI
So this proves that the angles GLH and HLI have the same measure, therefore ray LH is bisector of GLI.
Fourth option: m∠GLI = 1/2m∠GLH + 1/2m∠HLI
There are all angles we are interested in, but there is a mistake. We can see in the picture that angle GLI is made of angle GLH and HLI and not of half of them. This just is not true. The correct equation would be m∠GLI = m∠GLH + m∠HLI.

- The standard deviation is a better measure of spread for movies than it is for - basketball games.
- The IQR is the best measurement of spread for games and movies.
- The standard deviation is the best measurement of spread for games and movies.
The standard deviation is a better measure of spread for movies than it is for basketball games.
What is box- plot?A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.
As, Movies is more centric to mean and not skewed on a particular side whereas basketball games is not centric to mean but is skewed right then left.
Now, Standard deviation just measures the deviation or spread with respect to mean of collected data.
So, In the movies the data is more collected. Thus standard deviation is best suited for movie data.
Now, interquartile range. IQR relies on if the data is skewed.
So, in the basketball data the standard deviation will not give the information.
Hence, the standard deviation is a better measure of spread for movies than it is for basketball games.

F(x₂) = x²₂ - 6x₂ + 10 = (8)² - ( 6 x 8 ) + 10 =
F(x₂) = 64 - 48 + 10
F(x₂) = 26
F(x₁) = x²₁ - 6x₁ + 10 = (4)² - ( 6 x 4 ) + 10 =
F(x₁) = 16 - 24 + 10
F(x₁) = 2
