If A (1,-2) and B (5,-6) are the ends of the diameter of circle, then the radius and centre point of the Circle |
|
Answer» Step-by-step explanation: Centre is the mid point of diameter-> (x1+x2)/2 , (y1+y2)/2 (1+5)/2 , (-2-6)/2) 6/2 , -8/2 By distance formula _____________ d= A0=radius= √ (x1-x2)²+(y1-y2)² ___________ = √ (1-3)²+(-2+4)² ________ = √ (-2)²+(2)² _______ = √ 4+4 ____ = √ 8 __ = 2√ 2 UNIT Answer- centre(3, -4) radius= 2 √2 units |
