Displacement of a person moving from A to B along a semicircular path of radius R is 100 m. What is the distance travelled by him ?

Explanation

To solve the problem of finding the distance traveled by a person moving from point A to point B along a semicircular path of radius R, given that the displacement is 100 m, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Displacement**:
- Displacement is the shortest distance between the initial and final positions. In this case, the displacement from point A to point B along the semicircular path is given as 100 m.

2. **Relating Displacement to Radius**:
