Point of radius

WebRadius Formula. Before we begin with the radius formula, let us recall what is a radius. Radius is one of the important parts of a circle. Radius is the distance from the center of the circle to any point on its circumference, which means the line segment that connects the center of a circle to any point on its circumference is called the radius. WebIn all cases a point on the circle follows the rule x 2 + y 2 = radius 2 We can use that idea to find a missing value Example: x value of 2, and a radius of 5 Start with: x2 + y2 = r2 Values we know: 22 + y2 = 52 Rearrange: y2 = 52 − 22 Square root both sides: y = ±√ (52 − 22) Solve: y = ±√21 y ≈ ±4.58...

WebOC is perpendicular to AC (line tangent to a circle is perpendicular to the radius drawn to the point of tangency), making OAC a right triangle. OA is the hypotenuse, OC and AC are the legs. So you can set the equations for the Pythagorean Theorem: 1) 4^2+x^2= (2+x)^2. 16+x^2=4+4x+x^2. 16=4+4x. 12=4x.
