Solution for Problem 7

Show that the point 2rad2 lies on a circle whose center is the origin and contains the point (0,3).

ANSWER:
The radius of this circle is 3 units. The equation of this circle centered at the origin is x2 + y2 = 9.

If 2rad2 lies on the circle, it will make the equation true.

2rad2=rad8
(1)2 + (rad8)2 = 9
1 + 8 = 9
9 = 9 TRUE.
