Write an equation of the circle with the given center and radius.
-$( 8,7 ) ; 8$
A) $( x - 7 ) ^ { 2 } + ( y - 8 ) ^ { 2 } = 8$
B) $( x + 8 ) ^ { 2 } + ( y + 7 ) ^ { 2 } = 64$
C) $( x + 7 ) ^ { 2 } + ( y + 8 ) ^ { 2 } = 8$
D) $( x - 8 ) ^ { 2 } + ( y - 7 ) ^ { 2 } = 64$

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 with center $(8, 7)$ and radius $8$, the equation is $(x - 8)^2 + (y - 7)^2 = 8^2$, which simplifies to $(x - 8)^2 + (y - 7)^2 = 64$.
