If rose bushes are spaced about $1$ foot apart, approximately how many bushes are needed to surround a [circular](https://artofproblemsolving.com/wiki/index.php/Circle) patio whose radius is $12$ feet?
$\text{(A)}\ 12 \qquad \text{(B)}\ 38 \qquad \text{(C)}\ 48 \qquad \text{(D)}\ 75 \qquad \text{(E)}\ 450$
The [circumference](https://artofproblemsolving.com/wiki/index.php/Circumference) of the patio is $2\cdot 12\cdot \pi =24\pi \approx 75.398$.  Since the bushes are spaced $1$ foot apart, about $75\rightarrow \boxed{\text{D}}$ are needed.
