The length of each side of a square is twice the radius of a circle. If the radius of the circle is 7 cm, then what is the difference between the areas of the square and the circle? [Use π = $\frac{22}{7}$]

42 cm²

We know that,

The area of a circle = πR² 

Area of a square = (Side)²

We have,

The length of each side of a square = twice the radius of a circle.

The radius of the circle = 7 cm.

Side of the square = 7 × 2 = 14 cm

Area of the square = 14² = 196 cm²

Area of the circle = \(\frac{22}{7}\) × 7² = 154 cm²

So, the difference between the areas of the square and the circle = 196 - 154 = 42 cm²
