Answer:
Step-by-step explanation:
The equation for a circle is

We have an h, k, x, and y; we need to find r-squared. Filling in:
which simplifies to
which simplifies to
which means that

Our equation, then, is

12inches/1 foot
Hope this helps
I'm not to clear on what this triangle is trying to say but if 18 is a side and 12 is a side let's use the Pythagorean theorem to solve for the other side
18²=a²+12²
324=a²+144
180=a²
√180 = a
13.41 =a
since x look about twice a
x=2*13.41
x=26.8
