Question

Find the radius of the circle if the center is at (1, 2) and the point (-5, 6) lies on the

circle

Answer 1

7.21 is write answers brooooooooo

Answer 2

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

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=√((x_2-x_1)^2+(y_2-y_1)^2)`

`Radius=√((-5-1)^2+(6-2)^2)`

`Radius=√((-6)^2+(4)^2)`

`Radius=√(36+16)`

`Radius=√(52)`

`Radius=7.2111`

`Radius\approx 7.21`

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