Question

World vertices of a rhombus lie on a circle find the area of the rhombus if the area of circle is 1256 cm square

Answer 1

here's how we do this. since all the vertices like on the circle all the angles are 90.
we know the area of circle is 1256 so area of circle =radius *radius *3.14(pi) from this we get radius equal to 20.
now we get diameter =40cm and diagonal length of rhombus is equal to diameter.
now we can divide the square into two triangles with height=radius and base=diameter. so we get area of two equal triangles=2*1/2*base*height=20*40=800cm square .
so the area of rhombus=800 cm square
