Which of the following is the equation of a circle whose center is at the origin and whose diameter has endpoints (-1, 2) and (1, -2)?

Equation of circle x² + y² = 5

Step-by-step explanation:

Given  circle whose origin is at center, (g , h) = (0 , 0)

And end points of diameter = (-1 , 2) and (1 , -2)

So, Distance of diameter =

So , Diameter =

or, Diameter = =

Or, D = 2  unit

Now Radius = =  }{2}" alt="\sqrt{2}" />}{2}" />

so, Radius ( r) = unit

SO, equation of circle is

(x -0)² + (y - 0)² = r²

i.e Equation of circle x² + y² = 5    Answer

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
