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 …

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).

And the important things that we need to think about when we want to know what the volume of a cone is we definitely want to know the radius of the base. So that's the radius of the base.

In the distance formula, since "c" is replaced with the variable "d" (for distance). And in the equation of a circle, "c" is replaced with the variable "r" (for radius).

The circumference of a circle is its perimeter. To calculate it, use the formula 2πr, where r is the radius of the circle. The area of the circle can be found by the formula πr^2.

We want to know the radius of the circle created, or rather 1/R, which is curvature. The unit tangent vector is not given by dT/ds, but rather by T. dT/ds is asking how fast the tangent …

If you start from the circumference formula, C=2πr, to isolate the r, you have to divide by 2π, thus r= C/ (2π).

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, - …

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.

L is equal to mass times tangential velocity, or actually well yeah, tangential velocity, or the velocity that's perpendicular to the radius, times the radius. Now what happens, if we assume …
