The points (11,2) is the centre of the circle passing through the point (1,2) then the radius of the circle is​

Answer 1

Step-by-step explanation:

use distance formula

$\sqrt(x2 - x1)^{2} + (y2 - y1)^{2}$

put the values ( you can take any of given as x2 or X1)

$\sqrt{} (11 - 1) ^{2} + (0 ^{2} )$

→ 10 units
