There are only 4 radii in a circle.
A radius is a straight line that connects the center of the circle with a point on the circle itself.
Therefore, the answer is incorrect, as there are infinite radii.
False
Is there sufficient data to determine that
\( GH=AB \)
When you use a compass, you might see 4 construction marks, but mathematically, a circle has infinite points on its circumference. Each point can connect to the center, creating infinite radii!
Yes! Every radius in the same circle has exactly the same length. That's what makes it a perfect circle - all points are equidistant from the center.
A diameter goes all the way across the circle through the center, while a radius goes from center to edge. There are infinite radii but infinite diameters too!
No, you can't physically draw infinite lines! But you can imagine or understand that every tiny point on the circle's edge could have a radius drawn to it.
Absolutely! Whether it's a tiny circle or a huge one, every circle has infinite radii because every circle has infinite points on its circumference.
