Diameter of circle equation
WebThe circumference, C, of a circle is a measure of the distance around the circle. It can be found using the formula C = 2πr where r is the circle's radius. If using the diameter, d, of the circle: C = πd If the area of the circle, A, is known: Area formula of a circle The area of a circle is the plane region bounded by the circle's circumference. WebCalculate the area, circumference, radius and diameter of circles. Find A, C, r and d of a circle. Given any 1 known variable of a circle, calculate the other 3 unknowns.

WebThis means that, using Pythagoras’ theorem, the equation of a circle with radius r and centre (0, 0) is given by the formula \(x^2 + y^2 = r^2\). Example Find the equation of a circle with ... WebA line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another on the circle's circumference is called a Chord. If it passes through the center it is called a Diameter. And a part of the circumference is called an Arc.
WebDiameter Form of Circle Equation The equation of the circle drawn on the straight line joining two points ( x 1, y 1) and ( x 2, y 2) is ( x − x 1 ) ( x − x 2) + ( y − y 1 ) ( y − y 2) = 0. This is known as diameter form of circle. where ( x 1, y 1) and ( x 2, y 2) are coordinates of two ends of diameter of circle.
