Find an equivalent equation in polar coordinates.
-$$x ^ { 2 } + y ^ { 2 } = 100$$
A) $r = 10 \cos \theta$
B) $r = 100$
C) $r = 10 \sin \theta$
D) $r = 10$

Question

Quizplus · Accepted Answer

The given equation $x^2 + y^2 = 100$ is a circle with a radius of 10 centered at the origin. In polar coordinates, this translates directly to $r = 10$, since $r$ represents the distance from the origin to a point on the circle.
