Segments in a circle using CSS3

Yes, you can get such slices of custom angles using either one of the following two methods:

  1. If you don’t need the slices to be elements themselves, the you can simply do it with one element and linear gradients – see this rainbow wheel I did last month.
  2. If you need the slices to be elements themselves, then you can do it by chaining rotate and skew transforms – see this circular menu I did a while ago.

For #2, see also this very much simplified example I did right now.

.pie {
  overflow:hidden;
  position: relative;
  margin: 1em auto;
  border: dashed 1px;
  padding: 0;
  width: 32em; height: 32em;
  border-radius: 50%;
  list-style: none;
}
.slice {
  overflow: hidden;
  position: absolute;
  top: 0; right: 0;
  width: 50%; height: 50%;
  transform-origin: 0% 100%; 
}
.slice:first-child {
  transform: rotate(15deg) skewY(-22.5deg);
}
.slice-contents {
  position: absolute;
  left: -100%;
  width: 200%; height: 200%;
  border-radius: 50%;
  background: lightblue;
}
.slice:first-child .slice-contents {
  transform: skewY(22.5deg); /* unskew slice contents */
}
.slice:hover .slice-contents { background: violet; } /* highlight on hover */
<ul class="pie">
  <li class="slice">
    <div class="slice-contents"></div>
  </li>
  <!-- you can add more slices here -->
</ul>
