We'll need to modify our Torus' Last Operator. To open the Lat Operator panel you can click on the Add Torus button at the bottom of the 3D Viewport.

Once you have the Add Torus pannel open you will modify the values of the Major Segments to 32, and set the Major Radious to .39 m

Major Segments: This parameter specifies the number of segments in the main ring of the torus. It determines how many times the cross-sectional circle is duplicated around the central axis. Increasing the number of segments results in a smoother, more circular appearance.

Minor Segments: This setting controls the number of segments in the cross-sectional circle of the torus. Higher values lead to a more refined and smoother cross-section, enhancing the overall smoothness of the torus.

Major Radius: This determines the distance from the center of the torus to the center of its cross-sectional tube. Adjusting the Major Radius changes the overall size of the torus's main ring.

Increasing the Major and Minor Segments can smooth a ring, but maxing them can impact performance and make editing cumbersome. Instead, use Shade Smoothing and Subdividing your Surface.
