To write the equation of circle j, you need to know the center coordinates and the length of the radius. you already know that the center is at the origin, which is (0,0) so h=0 and k=0. and you also know that the diameter is 18, and since a radius equals one half of the diameter, r = 18 2 = 9, so the radius is 9. To write the equation of a circle in general form, simply expand the two brackets in its standard form (𝑥 – a) 2 (y – b) 2 = r 2. then collect like terms. for example write the equation of a circle with centre (2, 0) and radius 1 in general form. step 1. write the equation of a circle in standard form using the centre and radius. We need to find the equation of a circle in the form (x h)^2 (y k)^2=r^2, which means we need to find the center point and the length of the radius. now let’s count from the center to a point on the circumference to find the length of the radius. the radius is so r=3. now let’s plug everything into the standard form of a circle.
How To Solve Problems Based On Standard Equation Of A Circle Vol 1 To write the equation of a circle in general form, simply expand the two brackets in its standard form (𝑥 – a) 2 (y – b) 2 = r 2. then collect like terms. for example write the equation of a circle with centre (2, 0) and radius 1 in general form. step 1. write the equation of a circle in standard form using the centre and radius. We need to find the equation of a circle in the form (x h)^2 (y k)^2=r^2, which means we need to find the center point and the length of the radius. now let’s count from the center to a point on the circumference to find the length of the radius. the radius is so r=3. now let’s plug everything into the standard form of a circle. 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. So when we plot these two equations we should have a circle: y = 2 √[25 − (x−4) 2] y = 2 − √[25 − (x−4) 2] try plotting those functions on the function grapher. it is also possible to use the equation grapher to do it all in one go.
