Question

Find the diameter of the circle whose centre is at (2,0)
and which passes through the point (7, -12).
​

Answer 1

Answer:

the diameter is 26

Step-by-step explanation:

x1 =2. y1=0

x2=7. y2=-12

distance between 2 points

=√((x2-x1)^2+(y2-y1)^2)

=√((7-2)^2+(-12-0)^2))

=√(5^2+(-12)^2)

=√(25+144)

=√169

radius=13

diameter=radius×2

=13×2

=26
