Question

please answer my question​

Answer 1

Given,

1) InAOB,

AB, distance travelled from A to B= root over of AO^2 +OB^2

(By Pythagoras theorem).

= root of r^2+r^2

=root 2r^2. =root 2r.[ans.]

2) Distance travelled from A to C=AO+OC = r+r. =2r [ans]

As, AO=OC=r i.e radius of the circle.

3) In AOD AO=OD=r

So,AD=root of AO^2 +OD^2

=root r^2+ r^2

=root2 ❌r.

4). Distance travelled by the particle in one complete revolution= Circumference of circle= 2♊r .[ans].

Thank you!
