Question

PLS help me i am in a test

Find the coordinates of the centre of a circle if (3,-2 ) and (5, 4) , are the end points of its
diameter. Also, find the length of the radius of the circle

Answer 1

Answer:

√10 is radius of the circle

Answer 2

Answer:

coordinate of the centre of the circle:

X1=3, X2= 5, y1=-2, y2=4

X3=(X1+X2)/2 =8/2=4

y3=(y1+y2)/2=-2+4/2=1

length of the radius =( (x3-x1)^2 + (y3-y1)^2)^1/2

=(1+9)^1/2

=10^1/2= 3.162
