Creating pentagon shape with arcs

I need to create the ourter top view edge of this pentagon shape. That is a puffed pentagon with rounded corners too. Does Rhino have an easy way of doing this?

2 ways:
Make sure all curves in the pentagon are degree 3, 4 points.
Turn points on and select all of the non-corner points
Use MoveUVN or scale to move those points.
Find pentagon’s center point
Modify one of the curves of the pentagon
Polar Array that modified curve to make a new pentagon with curved sides.

Probably method 2. is the best approach if perfect pentagonal symmetry is the desired final result. Then, to fulfill the OP’s final desire: fillet the corners.

Yep method 2 worked just fine, thanks.
