Find the parametrization for the curve.
-The circle with center $( 7,9 )$ and radius 2
A) $x = 7 + 4 \cos t , y = 9 + 4 \sin t$, for $0 \leq t \leq 2 \pi$
B) $x = 7 + 2 \cos t , y = 9 + 2 \sin t$, for $0 \leq t \leq 2 \pi$
C) $x = 7 + 2 t , y = 9 + 2 t$, for $0 \leq t \leq 2 \pi$
D) $x = - 7 + 2 \sin t , y = - 9 + 2 \cos t$, for $0 \leq t \leq 2 \pi$

The correct parametrization for a circle with center $(h, k)$ and radius $r$ is $x = h + r \cos t, y = k + r \sin t$, for $0 \leq t \leq 2\pi$. Here, $h = 7$, $k = 9$, and $r = 2$, so the correct parametrization is $x = 7 + 2 \cos t, y = 9 + 2 \sin t$, for $0 \leq t \leq 2\pi$.
