a) Draw the curve for three complete revolutions of the circle.
b) Find the area between the curve (one loop) and the line.
c) Find the length of the curve - all three loops.
The arc length of one hump of a cycloid is marked by:
L = 8r (where r is the radius of the circle)
The area under the curve is marked by:
A = ...
I show how to calculate the area of a cycloid and the length of three complete revolutions.
