Answer:
The length of one of the spoke is 7 m
Option C is correct answer.
Step-by-step explanation:
Area of Ferris Wheel = 154 square meters.
We need to find the length of one of the spokes.
We are given: Assume the spokes go from the centre to the edge of the Ferris wheel.
So, We are given area of circle and we need to find radius of circle.
The formula used is: 
Putting values and finding radius
So, Radius of circle = 7 m
The length of one of the spoke is 7 m
Option C is correct answer.
Answer: 
Step-by-step explanation:
Green = g
Blue = b
Red = r
g+b = 1500
g+r = 750
g+b+r = 2000
in the 1st equation solve for b
g+b =1500
b = 1500-g
2nd equation solve for r
g+ r = 750
r = 750-g
now substitute the answers fro. b and r into the final equation.
g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250
So we k own the green bike is $250.
Blue = 1500- g
blue = 1500-250= $1250
red = 750-g
red = 750-250 = $500
After
using a calculator to find sin 21 degrees and rounding it to four decimal places,
I got 0.3584. The correct answer between all the
choices given is the first choice. I am hoping that this answer has satisfied
your query and it will be able to help you in your endeavor, and if you would
