First, for the measure of each central angle between gondola cars:
There are 41 glass-enclosed gondolas, the sky wheel is a circumference so the total angle is 360°. In order to find the measure, we can do the division 360/41
360°/41=8.78°
Therefore the result is 8.78°
For the radius, we can use the fact that the radius is half of the diameter
So, radius=diameter/2
r=181/2=90.5
The radius is 90.5 ft
