You cannot round polygon so here is a different idea using transformation:
.activity {
width: 200px;
}
.activity__icon {
text-align: center;
margin: 0 auto;
padding: 2rem;
position:relative;
z-index:0;
}
.activity__icon::before {
content:"";
position:absolute;
z-index:-1;
width:141px; /* 200px / sqrt(2) */
height:141px; /* 200px / sqrt(2) */
left:50%;
top:50%;
background-color: #eee;
transform:translate(-50%,-50%) rotate(45deg) rotate3d(1,-1,0,65deg);
border-radius: 28px 0 20px 0;
}
.activity__icon i {
color: #707070;
border: 2px solid #707070;
border-radius: 50%;
padding: 15px;
font-size: 25px;
text-align: center;
vertical-align: middle;
}<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css">
<div class="activity">
<div class="activity__icon"><i class="fas fa-play-circle"></i>
</div>
