Which explains how to find the radius of a circle whose equation is in the form x2 y2 = z?

ansver

If the expression is x^2 + y^2 = z, means that the radius is √z.

That is because the general expression of a circle with the center at the origin of the coordinate system is x^2 + y^2 = (radius)^2

Then in your expression z = (radius)^2, and the radius is found by taking square root>

√(radius)^2 = √z

=>radius = √z

ansver

The radius is the square root of the constant term, z.

makes sense, also took the test :)

ansver

z would be your radius

Step-by-step explanation:

Equation: (x - h)² + (y - k)² = r²

Simply take √r² to find r, your radius.

ansver

The standard form of the equation for a circle with radius r, centered at (h,k) is
(x - h)^2 + (y - k)^2 = r^2

The given equation is
x^2 + y^2 = z

Therefore h=0, k=0, and the circle has its center at the origin.
The radius is given by
r^2 = z => r =√z

The radius is the square root of the constant term z.

ansver

We know that
the equation of a circle is
(x-h)²+(y-k)²=r²
where
(h,k) is the center
and
r is the radius

in the problem
we have
x² + y² = z
so
the center is the origin (0,0)
and the radius r² is z
r²=z> r=√z

the answer is
The radius is the square root of the constant term, z
