Question

The standard form equation: x2+y2=16, what is the general form for this equation

Answer 1

The equation of the circle with radius 4.

Explanation:

The given equation is
`$ x^2 + y^2 = 16 $`.

General equation of the circle is
`$ (x - h) ^2 + (y-k)^2 = r^2 $`

where:
`$ (h, k) $` is the centre of the circle and
`$ r $` is the radius.

Here the centre is
`$ (0, 0) $` and radius is
`$ 4 $`.

Therefore this is the equation of the circle with centre
`$ (0, 0) $` and radius
`$ 4 $`.
