Question

if co-ordinate of and of diameter are( - 4,0)and (4,0) then what are the co-ordinate of centre of circle?
plz give right answer it's my TERM-1 exam​

Answer 1

Answer:

so I give example of your questions / and they are

same to same

because tommerow your term so prectise and answer itself so you learn better

Let AB be a diameter of the circle having its centre at C(1, -3) such that the coordinates of one end A are (4, -1).

Let the coordinates of B be (x,y).

Since C is the mid-point of AB. Therefore,the coordinates of C are(

2

x+4

,

2

y−1

).

But, the coordinates of C are given to be (1,-3).

∴

2

x+4

=1and

2y−1

=−3

⇒x+4=2andy−1=−6

⇒x=−2andy=−5

Hence,the coordinates of B are (-2, -5).
