A point moves quarter of a circle on the circumference of a circle of radius R. Find the distance travelled and displacement in terms of R.

Explanation

To solve the problem of a point moving a quarter of a circle on the circumference of a circle of radius \( R \), we need to find both the distance travelled and the displacement.

### Step-by-Step Solution:

**Step 1: Understanding the path travelled.**
- The point moves along the circumference of a circle. A quarter of a circle means the point travels along \( \frac{1}{4} \) of the full circumference.

**Step 2: Calculate the circumference of the circle.**
