Find the area of the square, if it’s inscribed in a circle whose radius is 3 m.1). 9 m22). 11 m23). 18 m24). 12 m2

Answer»

RADIUS of circle = 3 m2

Square is INSCRIBED in a circle, which means the diameter of circle is the diagonal of square.

⇒ Diameter of circle = 2 × radius = 2 × 3 = 6

Diagonal of square = 6

We know,

⇒ Side2 + Side2 = Diagonal2

⇒ 2 × side2 = 62

⇒ 2 × side2 = 36

⇒ Side2 = 18

⇒ We know, area of square = side2

∴ Area of square = 18 m2
