How can I create a circular arc of icons around a floating action button with clickable tooltips

I am working on a web project and I have a floating action button that is positioned at either the bottom right or bottom left corner of the screen. When I click on this button, four icons are displayed vertically above the button.

Currently, the icons appear in a vertical layout above the floating action button. However, I want the icons to be arranged in a circular arc around the button, maintaining their vertical order. Additionally, I would like to implement clickable tooltips for each icon, showing some information when the user hovers over them.

Below is the image of my requirement.

<div class="adminActions">
  <input type="checkbox" name="adminToggle" class="adminToggle" />
  <a class="adminButton" href="#!"><i class="fa fa-cog"></i></a>
  <div class="adminButtons">
    <a href="#" title="Add Company"><i class="fa fa-building"></i></a>
    <a href="#" title="Edit Company"><i class="fa fa-pen"></i></a>
    <a href="#" title="Add User"><i class="fa fa-user-plus"></i></a>
    <a href="#" title="Edit User"><i class="fa fa-user-edit"></i></a>
  </div>
</div>
