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

the answer is mp

step-by-step explanation:

5
