How can you create an empty circle using exclusively CSS?-CodePudding

I would like to create an empty half circle in CSS/SASS, here's my code snippet for the half circle, here's the output:

.half-circle{
width: 60px; 
height: 120px; 
border-radius: 60px 0 0 60px;
background: #15DEA5;
}

<body>

<div class ="half-circle"></div>
</body>

But I want to “empty” it from the inside, here's a screenshot of the result I want to achieve:

So is it possible to create an emptied half circles in CSS?
