Welcome to visit Our class1. The equation of the circle with the center and radius R is:has center , radius (with 2. The circle equation :CHECK THE OLDEST LESSONTopic: THE EQUATION OF THE CIRCLEType 1:Find the centers and radius of the following circles Type 2: Write the equation of the circlesExercise 1: Find the centers and radii of the following circles:SolutionCenter I(-2;4), radius R=4 Topic: THE EQUATION OF THE CIRCLE 1.The circle (C) : with center and radius is:MULTIPLE CHOICE QUESTIONSB 2.The circle (C): with center I and radius R is:MULTIPLE CHOICE QUESTIONSExercise 2: Write the equation of the circles (C) in the following cases:Topic: THE EQUATION OF THE CIRCLEThe circle (C) has center and radius R = 4.b) The circle (C) has center and pass through Exercise 2: Write the equation of the circles (C) in the following cases:R= 4Topic: THE EQUATION OF THE CIRCLEThe circle (C) has center and radius R = 4.R???b) The circle (C) has center and pass through DExercise 2: Write the equation of the circles (C) in the following cases:Topic: THE EQUATION OF THE CIRCLEExercise 2: Write the equation of the circles (C) in the following cases:SolutionThe circle (C) has:Hence, the circle equation (C) is :R=4+ Radius: + Center Topic: THE EQUATION OF THE CIRCLEThe circle (C) has center and radius R = 4.R???b) The circle (C) has center and pass through DExercise 2: Write the equation of the circles (C) in the following cases:Topic: THE EQUATION OF THE CIRCLESolutionThe circle (C) has:+ Center + Radius: Hence, the circle equation (C) is :Exercise 2: Write the equation of the circles (C) in the following cases:Topic: THE EQUATION OF THE CIRCLEThe circle (C) has center and radius R = 4.b) The circle (C) has center and pass through c) The circle (C) has diameter with and (-1;-4)A=B=(-3;-8).d) The circle (C) has center is the origin O and tangent to the lineI+ + Radius :is the median of side Topic: THE EQUATION OF THE CIRCLEc) The circle (C) has diameter with and (-1;-4)A=(-3;-8).B=SolutionThe circle (C) has:Hence, the circle equation (C) is :We have : (C) tangent to the line ΔΔ+ Radius :O+ Center d) The circle (C) has center is the origin O and tangent to the lineTopic: THE EQUATION OF THE CIRCLESolutionThe circle (C) has:Hence, the circle equation (C) is :Exercise 2: Write the equation of the circles (C) in the following cases:Topic: THE EQUATION OF THE CIRCLEThe circle (C) has center and radius R = 4.b) The circle (C) has center and pass through c) The circle (C) has diameter with and (-1;-4)A=B=(-3;-8).d) The circle (C) has center is the origin O and tangent to the linee) The circle (C) passing through three points The equation of the circle (C) is :Since .We have the system of equations:e) The circle (C) passing through three points Topic: THE EQUATION OF THE CIRCLESolutionHence, the circle equation (C) is :MULTIPLE CHOICE QUESTIONSB3. Given two points A(1;-1), B(5;7). The equation of the circle with radius AB is.B4. The circle passing through three points A(0;2), B(-2;0) and C(2;0) has the equation.1.The circle (C) has center I(3;-2), and radius R = 7 has the equation is .2. The circle (C) has center I(3;2) and pass through M(5;3) has the equation.
