Circle and its elements?
A circle is the locus of a point which moves such that its distance from a fixed point is constant. .The fixed point is centre and fixed distance is radius of circle. Elements of circle are centre, radius and circumference.
A collection of points in the plane whose distance from fixed point is constant?
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
How do you find total distance and total time and then calculate them altogether?
Total Distance: Distance from some fixed point at end - Distance from the same fixed point at start. Total Time: Time at end - Time at start. Not sure what is meant by "calculate them altogether".
What does parabola mean in mathematical terms?
It is the locus of all points such that their distance from a fixed line (the directrix) is the same as their distance from a fixed point which is not on that line (the focus).
How many degrees equal 1 inch?
The question cannot be answered simply. A degree is a measure of angular displacement whereas an inch is a measure of linear displacement. If the angular displacement (in degrees) were measured at a distance r inches from some fixed point (the centre of rotation), then the linear displacement would be pi*r/180 inches.
