Answer:

point lies outside the circle

Step-by-step explanation:

SO THE POINT lies outside the circle if the distance between the center and the point is greater than the radius length if the distance is equal to the radius length then the point lies on the circle and if the distance is less than the radius length then the point lies inside the circle

so by using distance formula the distance between origin (0,0) and the point (5,-7) will be :

√25+49=√74 = 8.6 and the radius is 5*√2=7.07 so the distance is greater  than radius length so the point lies outside the circle

I REALLY HOPE THIS HELPS YOU
