Is this the correct punctuation the new student, having just arrived from france, spoke very little english.

The correct answer is yes, the sentence "The new student, having just arrived from France, spoke very little English." has a correct punctuation.

Explanation:

When we have information that is not relevant to the sentence, and it is placed between two commas, we are in the presence of sentence interrupters.

Everything inside the comma will be information we don't need to understand the sentence.

In this case we have the following sentence:

The new student, having just arrived from France, spoke very little English.

Let's see what happens if we remove what is located between the commas:

The new student spoke very little English.

As we can see, the sentence still makes sense, so we can interpret that the information was not relevant.

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
