WebWe can also find the radius of the circle if we wish. It is simply half of the diameter, which is given by the distance formula: D = √ ( (x2 – x1)2 + (y2 – y1)2) D = √ ( (6 – 0)2 + (-8 – 0)2) D = √ ( (6)2 + (-8)2) D = √ (36 + 64) D = √ (100) D = 10 So the diameter is 10, and the radius is 5. WebA circle is the set of all points in a plane at a given distance (called the radius ) from a given point (called the center.) A line segment connecting two points on the circle and going through the center is called a diameter …
Web2 Answers Sorted by: 6 You have an isosceles triangle. You can use cosine formula for calculation the angle. c 2 = a 2 + b 2 − 2 a b cos ( α) a and b are sides next to the angle α, which are the radius of the center r. c is the distance between the two points P 1 and P 2. So we get: P 1 − P 2 2 = 2 r 2 − 2 r 2 cos ( α) WebJan 8, 2014 · How to find the equation of a circle given two pointsMore videos:Finding the equation of a circle given a midpoint and a radius:http://youtu.be/HBLoKLaDL4sFi...
