Question

hi can someone help me with geometry

Answer 1

your questions?

Answer 2

It's a multi-part question

Answer 3

A Ferris wheel is an amusement park ride comprised of a large wheel rotating on an axis. There are cars or compartments where people can sit or stand that are evenly spaced about the circumference of the circle. The wheel rotates slowly, taking passengers on a ride around the circumference of the circle.

Please select one of the following famous Ferris wheels to research:

Singapore Flyer
London Eye
Star of Nanchang
You will need to find the diameter and number of compartments (or cars) for the one you chose in order to be able to complete the calculations section of the assignment. Once you have your information, move on to step 2.

Answer 4

i selected the London Eye

Answer 5

ok and?

Answer 6

Complete the following tasks and calculations. You must show all work and steps to receive full credit.

Name of the Ferris wheel
Diameter of the wheel (in meters)
Number of cars or compartments
Circumference of the wheel (in meters)
Area of the wheel (in meters)
Measure of a central angle in degrees
Measure of a central angle in radians
Arc length between two cars or compartments
Area of a sector between two cars or compartments

Answer 7

i just need help walking through it

Answer 8

so obviously #1 would be The London Eye lol

Answer 9

you need the help from wikipedia

Answer 10

okay

Answer 11

they have the dimensions and all the details

Answer 12

okay thank you

Answer 13

yw

Answer 14

@Hero Hi. can you please help me. Wikipedia doesnt have this information and i need a bit more help

Answer 15

i can help you if you choose singapore flyer...the diameter is 150m

Answer 16

okay

Answer 17

but i do want to be walked through it

Answer 18

ok

Answer 19

theres 28 compartments

Answer 20

i was about to say that lol

Answer 21

i live in singapore btw. lol

Answer 22

really??? thats so cool!! i live in florida

Answer 23

cost SGD30 a ride there

Answer 24

wow 20 us dollars

Answer 25

now we got the first 3 problems out

Answer 26

now i have to find the circumference of the wheel

Answer 27

you know how to calculator that right?

Answer 28

the rest of the questions are calculations

Answer 29

not really

Answer 30

should i do it?

Answer 31

yea you should

Answer 32

i mean how should i do it?

Answer 33

circumference = diameter * pi

Answer 34

okay hold on

Answer 35

so is it 471??

Answer 36

yes

Answer 37

okay

Answer 38

471.239

Answer 39

try not to cut off too much of the decimals, it can affect your calculations later

Answer 40

now we have
Area of the wheel (in meters)
Measure of a central angle in degrees
Measure of a central angle in radians
Arc length between two cars or compartments
Area of a sector between two cars or compartments
to do

Answer 41

okay so how should i calculate the area?

Answer 42

\[A=\pi r^2\]

Answer 43

r is radius, correct??

Answer 44

yup

Answer 45

so r is c/2

Answer 46

547370.9643537529??

Answer 47

no

Answer 48

radius is d/2

Answer 49

OHH okay

Answer 50

55460.25?

Answer 51

no either

Answer 52

square your radius then multiply by pi

Answer 53

but the diameter is 150?

Answer 54

radius is half of diameter

Answer 55

Area = pi times radius squared

Answer 56

okay so since the radius is half of the diameter it would be 75

Answer 57

then mulitplied by itself it would be 5625

Answer 58

so then 5625*3.14 is 17662.5

Answer 59

correct

Answer 60

now for the central angle, it probably is asking the angle between 2 cars

Answer 61

okay so how should i calculate it?

Answer 62

360 divide by 28 which is the number of cars

Answer 63

12.8571

Answer 64

yes

Answer 65

now we have to convert that to radian

Answer 66

use this formula\[\theta \times \frac{ \pi }{ 180 }\]

Answer 67

what should i put in the calculator

Answer 68

the angle in degree multiply by pi

Answer 69

then divide by 180

Answer 70

0.22428

Answer 71

i have 0.224399 but it doesnt matter much

Answer 72

Okay

Answer 73

the unit for this is rad

Answer 74

so was that for number 6 or 7

Answer 75

Measure of a central angle in radians

Answer 76

oh what was the one in degrees?

Answer 77

12.8571

Answer 78

so now the arc length between two cars or compartments

Answer 79

mutliply the 0.22 something rad with the radius

Answer 80

okay
