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

= $\sqrt{2^2+5^2}$

= $\sqrt{4+25}$

= $\sqrt{29}$
