The diameter of a circle is the longest distance across the circle, which goes through the center of the circle. Diameter is twice the length of the radius, or the equation {eq}Diameter = 2radius {/eq}. Below is a diagram showing the radius and diameter of a circle, they are ...
Structural defects control the kinetic, thermodynamic and mechanical properties of glasses. For instance, rare quantum tunneling two-level systems (TLS) govern the physics of glasses at very low temperature. Due to their extremely low density, it is very
A perimeter is found by adding together the boundary sides of the shapes such as squares, rectangles and triangles. For a circle, the perimeter, also called the circumference, is found using the equation 2(pi)(r) where pi is 3.14159 and r is the radius of the circle.What...
Within the uncertainties of involved astronomical and biological parameters, the Drake Equation typically predicts that there should be many exoplanets in our galaxy hosting active, communicative civilizations (ACCs). These optimistic calculations are however not supported by evidence, which is often referre...
Given the position vectors of a point A and the center of a circle B of radius r, pA = [pAx; pAy]; pB = [pBx; pBy]; r = 2; Using this data alone, is it possible to find the position vectors of tangent points H and K drawn from point A to the circle B? I would then us...
1. The user-defined parameters are the minimum (rmin) and maximum (rmax) neighborhood radii and the number of steps when densifying the graph (nsteps). As initialization, the method first builds neighborhood-graph A using the maximum radius. Then the connected compon...
Thanks to Ismot from Bangladesh for the suggestion! A right triangle ABC has legs AB = 4, BC = 6, and has a semicircle O with its center on the hypotenuse tangent to the legs AB at D and BC at E. What is the radius of the semicircle?Problem...
The lower limit is typically the origin, and the upper limit can be determined by finding the furthest distance from the center of the curve. In AP Calculus, this is often done by finding the values of theta where r=0 and using those to integrate the area of one "leaf" of the curve...
We found about a dozen or so sheep by the small abode, clearing the hay by eating it down to the earth in the radius of their rope/stake situation. Aside from a few sheep, it seemed like we were the only living beings around up in those hills. The light was as clear as I’ve ...
The radius of the lane is calculated by the equation listed below: where the derivatives can be easily found from the second order polynomial coefficients fit in the lane line detection part. the position of the vehicle with respect to center is calculated by calculating the distance of the ima...
