# All the vertices of a rhombus lie on a circle. Find the area of the rhombus, if area of the circle is 1256 cm². (Use π = 3.14)

**Solution:**

Given, all the vertices of a rhombus lie on a circle.

Area of the circle = 1256 cm²

We have to find the area of the rhombus.

From the figure,

ABCD is a rhombus whose vertices lie on a circle.

d₁ and d₂ are the diagonals of the rhombus.

Area of circle = πr²

1256 = 3.14r²

r² = 1256/3.14

r² = 400

r = 20 cm

Therefore, the radius of the circle is 20 cm

Since all the vertices of the rhombus lie on the circle. The diagonal of the rhombus is equal to the diameter of the circle.

Diameter of circle = 2(20) = 40 cm

Area of rhombus = 1/2 × d₁ × d₂

= 1/2 × 40 × 40

= 20 × 40

= 800 cm²

Therefore, the area of rhombus is 800 cm²
