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

7.21 is write answers br

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

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

its 0.1 miles per minute

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
