help please!!! anyone?

Question

anonymous · Answer

Alright, so I am working on a worksheet where I had to find all these measures for a ferris wheel. I got most of them, I just need help with a couple of the findings.

anonymous · Answer

I got most of it:

2.	Diameter of the wheel (in meters)
165m
	3.	Number of cars or compartments
28
	4.	Circumference of the wheel (in meters)
C=πd
d-diameter 

C=π*165
=
518.4m
	
  5.    Area of the wheel (in meters)
A=πr2

A=π82.5^2 
=
21382.5m

	6.	Measure of a central angle in degrees
	7.	Measure of a central angle in radians
	8.	Arc length between two cars or compartments
	9.	Area of a sector between two cars or compartments

It is just those last four I guess, is there any formulas I can use for them?

I am guessing that you what the central angle between two cars in degrees and the same for question 7.

If that's what you want, then just divide 360 degrees by 28 to get the central angle. I would leave it as a mixed number.

Do the same thing for question 7.  Divide 2pi by 28 to get the angle in radians.

For question 8, divide the circumference by 28.

For question 9, divide the area by 28.
