Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure (Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is
__________________√(x2 - x1)2 + (y2 - y1)2. Test your program to cover all cases.) Two sample runs are shown below:
Enter a point with two coordinates: 4 5 ↵EnterPoint (4.0, 5.0) is in the circle
