00:00 - 00:59 | the question given here is find the equation of the circle which has its centre on the line Y is equal to 2 and which passes through the point 20 and 40 so let's construct a triangle we have we have expose this we have a line Y is equal to 2 the line Y is equal to 2 welcome status baby why it is today and the centre lies on from there on this point let's consider this point to be X2 Saudi the centre and which passes through the point to so where the 2020 is somewhere here |

01:00 - 01:59 | to AUDI access point 4 aur kaun hai re so that the circle passes through these two points so acid the circle can be like this so what we have to do is let suppose this align and we need to find the value of x so what will do here that we will the radius of the circle and use distance formula so the radius of the circle will be constant radius is equal to 8 which is it is constant for the circle so here |

02:00 - 02:59 | we have a from a distance formula we can find this much distance which is equal to x minus 2 whole square + 2 - 0 whole score under root which is equal to this distance so what you have you is under root of x minus 4 whole square + 2 - 20 square squaring both side cladding both side what is get x minus 2 whole square + 2 square equal to x minus 4 whole square + 2 square which is equal to write to square into square building cancel out and we will left with X square + 4 - 4 x is |

03:00 - 03:59 | equal to X square + 16 - 8 x x square x square equal cancel out here 8 x minus 4 x is equal to 16 - 4 in the term you will get equal to 12 so we will get the value of x to V3 so this is our centre extra cal to sleep now we need to find the equation of the circle we have asked equation of the circle equation settle hi can you download so we have x minus x-coordinate of the centre Y minus y co-ordinate of the centre |

04:00 - 04:59 | whole square is equal to radius square from here where I can also say that x minus 2 whole square + 2 - 0 whole square whole Power equal to 8 cm is equal to radius to the value of radius can be given as 3 minus 2 whole square + 2 square which is equal to 1 + 4 is equal to under root show the value of h radius is root 5 and now we can easily find the equation of the circle which is equal to x minus 3 whole square + 2 Y - 2 whole square is equal to 5 so this is the equation of the circle that we need to find thank you |
