Answer 1

Answer:

7.21 is write answers brooooooooo

Answer 2

Answer:

The radius of the circle is 7.21 units and option C is correct.

Step-by-step explanation:

It is given that center of the circle is at (1, 2) and the point (-5, 6) lies on the circle.

We need to find the radius of the circle. It means we have to o find the distance between (1,2) and (-5,6).

Using distance formula, we get

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$Radius=\sqrt{(-5-1)^2+(6-2)^2}$

$Radius=\sqrt{(-6)^2+(4)^2}$

$Radius=\sqrt{36+16}$

$Radius=\sqrt{52}$

$Radius=7.2111$

$Radius\approx 7.21$

Therefore the radius of the circle is 7.21 units and option C is correct.
