-$( 0,0 ) ; 14$
A) $x ^ { 2 } + y ^ { 2 } = 14$
B) $x ^ { 2 } + y ^ { 2 } = 196$
C) $x ^ { 2 } - y ^ { 2 } = 14$
D) $x ^ { 2 } + y ^ { 2 } = 28$

Question

Quizplus · Accepted Answer

The equation of a circle with center $(h, k)$ and radius $r$ is $(x - h)^2 + (y - k)^2 = r^2$. For a circle centered at $(0,0)$ with radius $14$, the equation is $x^2 + y^2 = 14^2$, which simplifies to $x^2 + y^2 = 196$.
