Aferris wheel car moves from point c to point d on the circle shown below:
circle a is shown with a central angle marked 38 degrees and the diameter marked 20 feet.
what is the arc length the car traveled, to the nearest hundredth?
2.18 feet
4.31 feet
5.84 feet
6.63 feet

The length of the arc that is traveled is equal to the product of the circumference and ratio of the angle to the total angle of 360°. mathematically expressing this concept,

length of the arc = c x (θ/360°)

circumference of the circle is calculated through the equation,
c = 2πr =  πd
where r is the radius and d is diameter.

substituting the known values,
length of the arc = (π)(20 ft)(38°/360°)

if we have the value of  π as 3.14,
length of the arc = (3.14)(20 ft)(38°/360°)
length of the arc = 6.63 ft

therefore, the answer is the last choice. 

The square root of 37 is 6.08. that means that no number squared can equal 37
