Question

solve the above problem​

Answer 1

Answer:

Let centre of circle be O(0,0) and the point be A(4,3)

OC is radius (dist. btwn centre and any point on the circumference )

Distance between 2 points = $\sqrt{(y_{2}-y_{1}) + (x_{2}-x_{1} ) }$

∴OC =  /(3-0)^2 + (4-0)^2

        = /9+16

        = /25 = 5 units

∴ radius is 5 units long
