Question

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

Answer 1

hey mate

here is the answer...

Answer:

r=√(x-h)²+(y-k)²

r=√(7-2)²+(-12-0)²

r=√(5)²+(-12)²

r=√(25+144)

r=√169

r=±13

thus,r=13 units (r≠-13)

thus,

diameter=2r

=2*13 units=26 units (Answer)
