No.
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
s the equator and the diameter the same thing?
No. Diameter is the distance across. Circumference is the distance around.
No, atomic mass and atomic diameter are not the same thing. Atomic mass refers to the mass of an atom, which is the sum of the protons and neutrons in the nucleus, while atomic diameter refers to the size of the atom, often measured as the distance between the nuclei of two bonded atoms.
the diameter divided by 2
No, motion and distance are not the same thing. Distance refers to the amount of space between two points, while motion refers to the change in position of an object over time. Motion involves the concept of distance but also incorporates the element of time.
Over the same distance the larger diameter wire will have less resistance that the smaller diameter wire.
That means that a given circle doesn't have two or three diameters. For a given circle, there is a unique measurement, called its "diameter". It is the distance from one end to the other, passing through the center. Since the circle is defined as all the points that are at the same distance from a point (the center), all radii are the same distance; and the diameter is simply twice the radius.
The angular diameter of the full moon is about 0.5 degrees. To calculate the distance at which a dime would have the same angular diameter, you can use the formula: tan(angular size) = (diameter of object) / (distance). Plug in the values and solve for distance to find that you would need to hold the dime approximately 68 meters away from your eye.
Diameter is the distance across, circumference is the distance around.
diameter?
A circle does not have a perimeter, but it has a circumference, which is pretty much the same thing. To find the circumference, multiply pi(3.14) times the diameter which is the distance across the center of the circle. I hope this helped
