A small ferris wheel, a student is riding a 20-m-diameter ferris wheel that is making 3 revolutions per minute. What is the area of the sector between 3 of the seats (3/8) of the wheel?

Answer 1

radius - 10 m
This has nothing to do with the speed. That is just given to confuse the student

Between three of the seats is also confusing because if there are 8 seats there is for example one at 0 degrees , one at 45 degrees and one at 90 degrees
so the area is 1/4, not 1/3 of the circle

1/4 of area of circle =(1/4)(pi r^2)
