  • Find the radius of the circle whose centre is (3, 2) and passes through ( - 5, 6)

Find the radius of the circle whose centre is (3, 2) and passes through ( - 5, 6)

Answers (1)

Given the center is (3,2) and circle passes through the point (-5,6). That is the point (-5,6) is on the circle.

Therefore the radius of the circle = distance between the points (3,2) and (-5,6)

=\sqrt{(-5-3)^2+(6-2)^2}=\sqrt{80}\ units​​​​​​​
