Equation Of A Circle Examples With Answers Write the general equation of a circle. x 2 y 2 = r 2x2 y2 = r2 for circles at the origin. 2 state any variables you know. the distance from the center (0, 0)(0,0) to the circle is 4.4. radius (r) = 4(r) = 4. 3 substitute any values you know into the equation. x 2 y 2 = 4 2x2 y2 = 42. Circle on a graph. let us put a circle of radius 5 on a graph: now let's work out exactly where all the points are. we make a right angled triangle: and then use pythagoras: x 2 y 2 = 5 2. there are an infinite number of those points, here are some examples:.
Equation Of A Circle Examples With Answers Practice questions on equation of circle. find the equation of a circle of radius 5 units, whose centre lies on the x axis and which passes through the point (2, 3). find the equation of a circle with the centre (h, k) and touching the x axis. show that the equation x 2 y 2 – 6x 4y – 36 = 0 represents a circle. also, find the centre and. R 2 (1) = p 2. r = p. where p is the radius of the circle. example: find the equation of the circle in the polar form provided that the equation of the circle in standard form is: x 2 y 2 = 9. solution: to find the equation of the circle in polar form, substitute the values of x x and y y with: x = rcosθ. y = rsinθ. Sometimes, the equation of a circle may not be presented in the neat ‘standard form’ as shown above. as an example, let us put some values to a, b, and rand expand the equation of a circle in standard form. let a = 2, b = 3, r= 4, then the equation becomes (x – 2) 2 (y – 3) 2 = 4 2. x 2 – 4x 4 y 2 – 6y 9 = 16. x 2 y 2. What is the standard form equaton of a circle? answer: another example. circle with a center of (2, 1) and a radius of 4 (3,1) , this circle's equation is.
