# Area of the circle obtained in Question 4 (A wire is bent to form a square of side 22 cm. If the wire is rebent to form a circle, its radius is 14 cm)

a. 196 cm²

b. 212 cm²

c. 616 cm²

d. 644 cm²

**Solution:**

A __circle__ is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane.

The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

The __radius of circle__ obtained in question 4 is 14 cm

We know that

__Area of a circle__ = πr²

Substituting the values

= 22/7 × 14 × 14

= 616 cm²

Therefore, the area of the circle is 616 cm².
