Circle equation review

[insert drawing of circle on graph with center point at (2, 3) and a radius r of 5] (x − a)2 + (y − b)2 = r2 x - a 2 + y - b 2 = r 2 (x − 2)2 + (y − 3)2 = 52 x - 2 2 + y - 3 2 = 5 2 Let's expand that so you can

Writing standard equation of a circle

The equation of a circle can be calculated if the centre and the radius are known. Thus the equation of a circle is given by (x-h) 2 + (y-k) 2 = r 2 Where (h, k) – centre coordinates r – radius

Equation Of A Circle

What is the standard form equaton of a circle? Answer : is a way to express the definition of a circle on the coordinate plane. The formula is ( x − h) 2 + ( y − k) 2 = r 2. h and k are the x and y coordinates of the center of the circle ( x − 9) 2 + ( y
