Athlete covers 2pi radians in 40 s. So angular velocity = pi / 20 rad/s
Hence the velocity = r w
r = 100 m. So v = 5 pi m/s
Hence the distance covered in 2 min 20 s ie 140 s = 700 pi metre.
Displacement is the shortest distance between initial and final position
In 140 s, 3 full rotation and one half rotation. So the he will be diametrically opposite. Hence the displacement is equal to 200 m ie diameter of the circular track.
Distance covered - 2199m Displacement - 200m Distance covered - 2199m Displacement - 200m
double of the radius means equal to diameter
After traversing 1/2 of a circular track with radius 'R', the body has effectively moved from one end of a diameter to the other end of the same diameter. The distance traveled is 1/2 the circumference = (pi)D/2 = (pi)R. The displacement is D = 2R. The ratio of displacement to distance = (2R)/(piR) = 2/pi= 0.63662 (rounded), independent of 'R'.
Circular diameter is the distance from side to side of a circle through the middle.
A diameter is a property of circular objects. "12 inches" is not a circular object and so cannot have a diameter.

Diameter is equivalent to the width of a circular object. Width is the shorter side of a non-circular two-dimensional object. The longer side is considered the length.
Circular diameter is the distance from side to side of a circle through the middle.

Distance is a function of displacement. You need to define the origininal position and the present position. The difference between them is the displacement, the distance is the measure (using accepted units) of the difference between the two.
Avalanches are not circular and so do not have a diameter, as such.
Only circular shapes have diameter not Squares.
If he covers 1/2 the length of the circular path, then the beginning and end of histrip are at opposite ends of a diameter of the circle.Diameter = 2 x radius = 2 x 5 = 10 meters.
Your question is incomplete. What is the question? Total diameter, outer circumference, what?
diameter = 220/pi meters
