The equation of the given circle is ( x^{2}+y^{2}=25 ) ( x^{2}+y^{2}=25 ) ( (x-0)^{2}+(y-0)^{2}=5^{2}, ) which is of the form ( (x-h)^{2}+(y-k)^{2}=r^{2}, ) where ( h=0, k=0, ) and ( r=5 ) Centre ( =(0,0) ) and radius ( =5 ) Distance between point (-2.5,3.5) and centre (0,0) ( =sqrt{(-2.5-0)^{2}+(3.5-0)^{2}} ) ( =sqrt{6.25+12.25} ) ( =sqrt{18.5} ) ( =4.3(text { approx. })<5 ) since the distance between point (-2.5,3.5) and centre (0,0) of the circle is less than the radius of the circle, point (-2.5,3.5) lies inside the circle.
