Circle radius

Circle by Point Radius

It's a circle with a radius of 1.

We call that the radius of the circle.

BE is equal to the radius of the circle

BC is equal to the radius of the circle

Once again, this is the radius of the circle

If that's psi, this length right here is a radius that's our radius of our circle.

So AB is equal to the radius of the circle

Which of the following must be the radius of the circle?

This is a circle and that's a constant radius.

formula_2where is the area of a circle and is the radius.

So that tells us the radius of the circle is 3.

So the answer is a circle with radius at minus 2 comma 3 and radius 4.

That's our radius, and we're ready to graph this circle.

A circle defined by its center and the length of the radius

This was the equation for a circle with radius 10, right?

BE, is one radius of the circle going from the center to the arc

length r. So this is going in a circle with radius r.

So let's call this, that's a radius right over here, the length of that is just going to be the radius of the circle, but I can also do it right over here, the length of AC is also going to be the radius of the circle.

And then they measure the radius of the circle right here or the diameter of that circle, and they'd say oh, the diameter

It is also a radius of the circle going from the center to the arc

We know that this right over here is equal to the radius of the circle

When you go from 0 to 2 pi radius, you've made 1 circle.

Radius OC and radius OA and that's useful for us because we know that they are both radii for the same circle

And we can keep drawing other things that are equal to the radius of the circle

There you go, so the 12 5 is the radius the radii of the circle, so this first circle ABD around a triangle ABD

That these are the exact same length, and this is equal to the radius of the circle

So we know that these two lines have the same length which is the radius of the circle, which is the radius of the circle or we can say that AD is congruent to AC or the have the exact same lengths.

We know that a radius connects a point to the center, so you have one radius right over here that connects F and A that's one radius and you have another radius connecting A and H, a point connecting to the center of the circle.

So let's say I have a circle just like that, and I were to tell you it has a radius it's radius right there is 3.

A and B both sit on the circle they are both a radius away from the center

I can get it to stack on itself 4 times to get the radius of this circle right over here

So that's the x axis, that's the y axis, then draw the circle itself, circle looks like close enough, and then the distance or the radius from the center of the circle, that's going to be 3.

Let me draw a well, it is a radius, but I'm going to go beyond the unit circle.

The general form of an equation, or the general equation for a circle, is x squared plus y squared is equal to r squared, where r is the radius of the circle.

So it looks like he took the pivot of his compass and he drew a circle around with a constant radius.

Imperial Russia used a system derived by dividing the circumference of a circle into chords of the same length as the radius.

And if you give me any point in space, any unique point, and a radius the set of all points that are exactly that radius away from it that defines a unique circle.

We know that when a line is tangent to a circle, it's perpendicular to the radius at that point.

Then this length right here is also going to be the radius of our circle going from the center to the circumference.

line segment, I should say, that connects the center to a point on the circle we would call a radius.

Let's say this radius is 3 when y is equal to 2, we're probably right around there on the circle.

In the diagram, θ is the central angle in radians, formula_1 the radius of the circle, and formula_2 is the arc length of the minor sector.

So the trick is to realize that this is a circle and so any any line that goes between B and any point on this arc is going to be equal to the radius of the circle
