Question1Circle A has a diameter of 9 cm. Circle B has a radius of 5 cm. Circle has the larger circumference by centimeters. Use LaTeX: \pi=3.14,Question2 A circle's circumference is approximately 44 cm. Complete each statement using one of these values: 7, 11, 14, 22, 88,138, 154, 196, 380, 616.
a. The circle's diameter is approximately cm.
b. The circle's radius is approximately cm.
c. The circle's area is approximately cm2.
Answer:
1.) CIRCLE B
2.) 14 cm ; 7cm ; 154cm²
Step-by-step explanation:
Given that:
CIRCLE A:
Diameter (d) = 9cm
CIRCLE B:
Radius (r) = 5cm
Circumference of circle A:
Radius (r) = diameter / 2
C = 2 * pi * r = 2 * 3.14 * (9/2) = 28.26 cm
Circumference of Circle B:
C = 2 * pi * r = 2 * 3.14 * 5 = 31.4 cm
CIRCLE B has the larger Circumference.
2.) circle with Circumference (C) = 44cm
Diameter of circle ;
C = 2 * pi * (d/2)
44 = 2 * 3.14 * (d/2)
44 = 6.28d / 2
88 = 6.28d
d = 14.01 = 14.0 cm ( 1 decimal place)
B.) Circle's Radius
Radius = diameter / 2
Radius = 14.0 / 2 = 7 cm
C.) Area (A) of the circle :
A = pi * r^2
A = 3.14 * 7^2
A = 3.14 * 49
A = 153.86
A = 154 cm²
Perpendicular Lines
Instructions: Given the following image is a cube, name a segment that is
perpendicular to AH?
Answer:
HG
Step-by-step explanation:
Where they meet another line at a 90 degree angle.
The segment that is perpendicular to segment AH in the given cube is: HG.
What are Perpendicular Segments?When two segments form a right angle at the point of their interception, they are said to be perpendicular to each other.
In the image given, a right angle is formed where segments AH and HG meet. Therefore, a name of a segment that is perpendicular to AH is: segment HG.

The math teacher gives each student a map of the amusement park that uses a coordinate plane. The meeting location is at (0, 0) on the map. Each unit is 100 feet. The first ride that you want to try is located at the coordinates (0, 4). The next ride is located at (3, 0). If you walked in a straight line from the first ride to the second ride, how many feet would you travel?
Answer:
500 ft
Step-by-step explanation:
use this formula
The actual distance between first and second ride is 500 ft.
What is Distance Formula?The distance between two point P(a, b) and Q(c, d).
so, the distance PQ = √(c-a)² + (d- b)²
Given:
Starting point = (0,0)
First ride = (0,4)
Second ride = (3,0)
In map, each unit = 100 ft
Using the distance formula
d = √( 3-0)² + (0-4)²
d = √9+ 16
d= √25
d = 5 units
So, the distance between first ride and second ride in the map is 5 units.
and,1 units = 100 ft
5 units = 500 ft
Hence, the actual distance between first and second ride is 500 ft.

Answer:
The length of [tex]\overline{AD}[/tex] is 20 inches
Step-by-step explanation:
The given parameters are;
Triangle ABC is similar to triangle DEC, therefore, we can write, ΔABC~ΔDEC
[tex]\overline{AC}[/tex] = 30 inches
[tex]\overline{BA}[/tex] = 18 inches
[tex]\overline{ED}[/tex] = 6 inches
By similar triangles formula, we have;
[tex]\overline{BA}[/tex]/[tex]\overline{ED}[/tex] = [tex]\overline{AC}[/tex]/[tex]\overline{DC}[/tex]
Substituting the known values gives;
18/6 = 30/[tex]\overline{DC}[/tex]
Therefore, [tex]\overline{DC}[/tex] = 30/(18/6) = 30/18 × 6 = 10
[tex]\overline{DC}[/tex] = 10
[tex]\overline{AD}[/tex] = [tex]\overline{AC}[/tex] - [tex]\overline{DC}[/tex] = 30 - 10 = 20
[tex]\overline{AD}[/tex] = 20 inches.

What is the slope of a line parallel to the line whose equation is 6x+9y=216. Fully reduce your answer.
Answer:
Solve the equation so it is in the y=mx+b form.
Step 1. 6x+9y = 216
Step 2. 9y = -6x+216
Step 3. y = -6/9x+24
Step 4. Simplify/Reduce to get y = -2/3x+24
Since it is Parallel then the slope is the same so the slope is -2/3x.

Line c passes through (2,0) and (4,4).
are parallel, because they have
Ja are perpendicular, because they
have slopes that are
Help!!!
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex. [tex]\frac{a}{b}[/tex] and [tex]-\frac{b}{a}[/tex] are perpendicular slopes.
Finding slope is using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Line a has slope [tex]\frac{3-4}{4-0}[/tex] = [tex]-\frac{1}{4}[/tex]
Line b also has slope [tex]-\frac{1}{4}[/tex]
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.
