Question

anitha completes three and half rounds along a circular track of radius 50 calculate her (a) displacement (b) distance travelled​

Answer 1

Answer:

To find the displacement, calculate the circumference of the circle and multiply it by 3 (since the athlete makes 3 rounds).

C = 2pi(r) = 100pi meters. 100pi * 3 = 300 pi meters, which is roughly equal to 942.48 meters.

The displacement is the distance between the athlete’s final and initial positions. Since the athlete makes three complete rounds around the track, their final position is at the starting point, therefore their displacement is zero.
