MAH-CET | Mathematics | 2026The circle whose diameter has endpoints (2,4) and (6,8) has centre:
Choose the correct answer:
- A.
(4,6)
(Correct Answer) - B.
(6,4)
- C.
(8,12)
- D.
(2,4)
(4,6)
Explanation
A key property of a circle is that the centre of a circle is the midpoint of its diameter.
Let the endpoints of the diameter be:
A(x1,y1)=(2,4)
B(x2,y2)=(6,8)
To find the coordinates of the centre, we use the Midpoint Formula:
Midpoint (x,y)=(2x1+x2,2y1+y2)
Now, substitute the given values into the formula:
For the x-coordinate:
x=22+6=28=4
For the y-coordinate:
y=24+8=212=6
Therefore, the coordinates of the centre of the circle are (4,6).
