Mathematics in the london eye answers

CENTRAL ANGLE: 
There are 32 passenger cars, so you want an angle equal to 1/32 of the full circle. 

The full circle in degrees is 360°, but you want radians. 
The full circle in radians is 2π. 
2π / 32 
= π/16 radians 

ARC LENGTH 
The arc length would be 1/32 of the full circumference. I know you already asked and got answers for the full circumference. Divide that by 32. 

AREA OF SECTOR: 
Ditto on this. You have the full area from a prior question. Now just divide it by 32
