Question

If the diameter of a circle has endpoints A (7,2) and B (-1,8), where is the center?

Answer 1

first we will get sum of X coordinates of A and B
secondly we will divide it by two
same sum the Y coordinates and divide it by
(-1+7)/2=3 and  (2+8)/2=5
so the center will be (3,5)
hope it helps

Answer 2

In the middle: x-coordinate= {7-(-1)}/2= 4 y-coordinate= (8-2)/2= 3 So centre is (4,3)
