The research shows that the name of the ferris wheel is <u>The London Eye</u> and the diameter of the wheel is 120m.
<h3>What is a research?</h3>
A research is simply carried out to get information about a particular topic or issue.
In this case, the research was conducted on the ferris wheel. The number of cars or compartments is 32.
The circumference of the wheel will be:
= 2πr
= 2π(120/2)
= 377m
The area of the wheel will be:
= πr²
= π(60²)
= 11310m²
The measure of a central angle in degrees will be:
= 360/32 = 11.25 degrees
The measure of a central angle in radians will be:
= 2π(11.25)/360
= 20 radians.
The arc length between two cars or compartments will be:
= 2π(60)(11.25)/360
= 11.78
The area of a sector between two cars or compartments will be:
= π(60²)(11.25)/360
= 353.43
An equation of a circle for your ferris wheel when the center of the ferris wheel is located at (0, 0) on a coordinate grid will be x² + y² = 3600.

Answer:
b
Step-by-step explanation:
Step-by-step explanation:
Draw the triangle formed by the ray.
The hypotenuse of the triangle is:
c² = a² + b²
c² = (-5)² + (2√7)²
c² = 25 + 28
c = √53
Therefore:
cos β = -5 / √53
Or, as a proper fraction:
cos β = -5√53 / 53
