This is how I would do it: I'm creating a path id="segment" and I'm using and rotate it 6 times:

let R = 45;// the outer radius
let r = 15;// the inner radius
//the radius for the text
let textR = r + (R - r)/2
// the angle for the slice
let A = Math.PI/3;
//points used to draw a slice
let p1 = {}
let p2 = {}
let p3 = {}
let p4 = {}
p1.x = r*Math.cos(-A/2);
p1.y = r*Math.sin(-A/2);
p2.x = R*Math.cos(-A/2);
p2.y = R*Math.sin(-A/2);
p3.x = R*Math.cos(A/2);
p3.y = R*Math.sin(A/2);
p4.x = r*Math.cos(A/2);
p4.y = r*Math.sin(A/2);
// the d attribute for the slice
let d =`M${p1.x},${p1.y} L${p2.x},${p2.y} A${R},${R} 0 0 1 ${p3.x},${p3.y} L${p4.x},${p4.y} A${r},${r} 0 0 0 ${p1.x},${p1.y}`;
// set the d attribute for the slice
sectorpath.setAttributeNS(null,"d", d);


// set the x and y attributes for the text
let text = document.querySelectorAll("#txt text")

text.forEach((t,i) =>{
  let x = textR * Math.cos(A*i - Math.PI/2);
  let y = textR * Math.sin(A*i - Math.PI/2);
  
  t.setAttributeNS(null,"x",x);
  t.setAttributeNS(null,"y",y);
})
svg{border:1px solid}
use{fill:blue; stroke:white; stroke-width:3}
<svg viewBox="-50 -50 100 100" width="300" >
  <defs>
    <path id="sectorpath" />
    <mask id="themask">
    <use xlink:href="#sectorpath" style="stroke:#000; stroke-width:3; fill: #ffffff"/>
    </mask>
    <use xlink:href="#sectorpath" id="sector" fill="blue" style="mask: url(#themask)"  />
  </defs>
  
  
  <use xlink:href="#sector" transform="rotate(-90)" />
  <use xlink:href="#sector" transform="rotate(-30)" />
  <use xlink:href="#sector" transform="rotate(30)" />
  <use xlink:href="#sector" transform="rotate(90)" />
  <use xlink:href="#sector" transform="rotate(150)" />
  <use xlink:href="#sector" transform="rotate(210)" />

    
</svg>
