What I'm trying to do is remove the svg lines in the middle of the circle.
How would this be done using clip-path?

<svg class="stack" aria-hidden="true" width="260" height="194" viewbox="0 0 260 194">
<line stroke="teal" x1="131" y1="40" x2="130" y2="149"></line>
<line stroke="dodgerblue" x1="91" y1="133" x2="170" y2="58"></line>
<line stroke="purple" x1="77" y1="95" x2="185" y2="96"></line>
<line stroke="green" x1="169" y1="135" x2="93" y2="56"></line>
<circle class="outer" cx="131" cy="95" r="55"></circle>
<circle cx="130" cy="95.40" r="20.8"></circle>
You will need to draw a path with a hole for the clipping path:
<path d="M0,0 0,194 260,194 260,0 0,0
M150.8, 95.40A20.8, 20.8 0 0 1 109.2 95.40A20.8, 20.8 0 0 1 150.8, 95.40" />
The first part of the path (M0,0 0,194 260,194 260,0 0,0
) is drawing a rectangle as big as the svg canvas. The second part (M150.8, 95.40A20.8, 20.8 0 0 1 109.2 95.40A20.8, 20.8 0 0 1 150.8, 95.40
) is drawing a circle as big as the inner circle and in the same position.
Next you wrap the lines in a group and you clip the group.
svg{border:1px solid;}
circle{fill:none;stroke:black}
<svg class="stack" aria-hidden="true" width="260" height="194" viewbox="0 0 260 194">
<defs>
<clipPath id="clip">
<path d="M0,0 0,194
260,194 260,0 0,0 M150.8, 95.40A20.8, 20.8 0 0 1 109.2 95.40A20.8, 20.8 0 0 1 150.8, 95.40" />
</clipPath>
</defs>
<g clip-path="url(#clip)">
<line stroke="teal" x1="131" y1="40" x2="130" y2="149"></line>
<line stroke="dodgerblue" x1="91" y1="133" x2="170" y2="58"></line>
<line stroke="purple" x1="77" y1="95" x2="185" y2="96"></line>
<line stroke="green" x1="169" y1="135" x2="93" y2="56"></line>

<circle cx="130" cy="95.40" r="20.8"></circle>
