If a point B(2,5) lies on a circle with center at origin,then what will be the length of the
lianna [129]

Answer:

r = \sqrt{29}

Step-by-step explanation:

The distance from the centre to a point on the circle is the radius r

Calculate r using the distance formula

r = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 5 )

r = \sqrt{(2-0)^2+(5-0)^2}

  = \sqrt{2^2+5^2}

  = \sqrt{4+25}

  = \sqrt{29}
