In which of the circles is the point marked inside of the circle and not on the circumference?
Let's remember that the circular line draws the shape of the circle, and the inner part is called a disk.
Therefore, in diagram B, the point is located in the inner part, meaning inside the disk.
Where does a point need to be so that its distance from the center of the circle is the shortest?
Interior points are completely surrounded by the circle with space around them. Circumference points lie exactly on the circular boundary line. Think of it like being inside a room versus standing in the doorway!
Look for empty space between the point and the circle's edge in all directions. If the point touches the circle line anywhere, it's on the circumference, not interior.
No! A point is either completely inside, exactly on the circumference, or completely outside. There's no in-between for geometric points.
Even if it's very close, as long as there's some space between the point and the circle boundary, it's still an interior point. Use careful visual inspection or measure the distance.
Understanding point positions helps with circle equations, inequalities, and coordinate geometry. Interior points satisfy while circumference points use equals.
