The radius is just the line from the center of the circle. The diameter goes all the way through the center. The circumference is the area around the circle. You find the radius by taking the diameter and …

The radius is the measurement of the middle point to the edge; it should be the same no matter which direction you measure to. A diameter is just radius x 2 (two radii).

On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing …

We call the radius of the circle associated with each point the radius of curvature at that point. It's a good way to measure how much a curve actually, you know, curves at each point. Another way to think …

So we could say that our radius of convergence is equal to 1. Another way to think about it, our interval of convergence-- we're going from negative 1 to 1, not including those two boundaries, so our …

The circumference of a circle and the area of a circle have one thing in common: the radius. If I were you I'd do it in two steps: - first calculate the radius using the circumference formula, - then calculate the …

Circle equation is the Pythagorean theorem but instead of a ^2 + b^2 =c^2 it's (x-k)^2+ (y-b)^2=radius^2. To find the radius all you need to do is square root the number after equal sign to get the radius. To …

Based on that, let's see if we can figure out what the radius of that same circle is going to be. And I encourage you, and I'll write equals here. And I encourage you to pause the video, and see if you …

What is circumference? Circumference is the distance around the outside of a circle (its perimeter!). Want a review of circle vocabulary terms (like pi, radius, and diameter)? Check out this video.

The radius of a sphere is half its diameter. So, to calculate the volume of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume.
