*In Exercises 11 to 22, sketch and describe each locus in the plane.*

Find the locus of points that are at a distance of 3 in. from a fixed point O.

To determine

**To find:**

The locus of points that are at a distance of 3 in. from a fixed point O.

Explanation

**Definition:**

A locus is set of all points and only those points that satisfy a given set of conditions.

It must be noted that, the phrase “all points and only those points” has dual meaning as follows:

1. All points of the locus satisfy the given condition.

2. All points satisfying the given locus conditions are included in the locus.

**Calculation:**

Step 1: Take any arbitrary point and label it as

Step 2: Take
