I'm not familiar with that one.  I know a circle as a "set of points all equidistant from a fixed point in a plane".\n\nI see where you are going with your definition, but I don't think it is worded well.  For one, it doesn't specify that these direction-changing lines are pivoting around a fixed point.  They could just be scattered all over the plane in which case, since they are infinite, you'd end up with a shaded in plane instead of a circle.  For another, they would need to be line segments instead of lines, and the endpoint would be what is creating the closed loop.  And which point on the line segment would they be pivoting around?  If it's one endpoint, then the line seg. would be the radius; if the midpoint, diameter.  Any other point on the line segment would create 2 circles.

Because it is the truth. Geocentric theory had placed the Earth at the certer of the Universe. We now know this to be incorrect. The heliocetric theory holds that the earth revolves around the sun and the sun is not the center of the universe. Chaos theory states that no place in the universe is special and that for us to presume that the earth is the center of the universe is False logic.

The radius of a circle is the distance from the center of the circle to the edge of the circle.

Central Tendency is used in Statistics to analyze a set of numerical data.  The purpose of of central tendency is to "measure" where the "center" of the data is located. Think of this measurement as a number which can be representative of the whole data set.  The most used central tendency measurements are:\n  - Mean: numerical average of a data set\n  - Median: the piece of data located in the center of the data set after it has been ordered.\n  - Mode: the data element(s) in the set that repeats the most.  Note that the Mode can  be more than one number if it happens that more than one particular number repeats the same amount of times.\n\nNormally, when analyzing a set of numerical data, not only the central tendency measurements are analyzed, but also disperssion measurements are taken into account.  \n\nDisperssion reffers to how "spread" is the data.  The most common disperssion measurements are:\n  - Standard deviation:  measuring how spread is the data around the Mean.\n  - Range: measures the distance from the smallest to the highest number in the set.\n\nHope this helps.\nAlberto

a cube isa rectangular solid whose l=w=h\n\n2.circle is the locus ofa moving point always equidistant from a fixed point\n\n3.A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat.\n\n4.a rectangle is a parallelogram whose angles are 90*\n\nnow that you knowwhat these are you can figure out the usage

According to Newton's first law of motion, a moving body travels along a straight path with constant speed (i.e., has constant velocity) unless it is acted on by an outside force.\n\nFor circular motion to occur there must be a constant force acting on a body, pushing it toward the centre of the circular path. This force is the centripetal (“centre-seeking”) force. The centrifugal (centre-fleeing) force will, therefore, be the opposing force which pushes away from the centre\n\nThe two forces are equal in magnitude and opposite in direction.

Hi. Co-axial means they share the same center-line. This useful for power transmission through a drive shaft or speakers in a small enclosure but does not require a theorem as far as I can see.

it would be called tangent...if it touches the outside of the circle once.\n\nthe radius of the circle is a line that goes through the cirlce half way, the diamiter is a line that goes through the circle and cuts it right in half, so the radius is half the diamiter.\n\nsecant intersects a cirlce at two points.\n\nSO the answer is tangent.\n\nhope this helps.

For many uniform configurations, the centroid is the center of gravity or the center of mass.  As I recall, I believe that the two may differ under certain circumstances where motion and acceleration is involved.  See the source for uniform materials and origin of the term.

Linear and centripetal would be two.  Linear is in a stratight line, centripetal is in a circle (the acceleration is towards the center constantly pulling the item off of a straight line).  Maybe the third one is some sort of combination...nonlinear and noncircular...that is my best guess.  Acceleration is a change in velocity or direction.
