Question

A person travels distance "pie r "along the circumference of a circle of radius R .Then find the distance ??

Answer 1

Answer:

The answer must be ' 2R '

Explanation:

Radius of circle is R

Person travels πR

Circumference of circle = 2πR

so, circumference of semicircle = πR

That means, person travelled a distance if half ( semi) circle. Therefore, he must be at a distance equal to diameter ie. 2× R = 2R
