MC II-A HW Questions

1) Regarding this week's HW, I'm not sure how to do 9.19 and 9.25.

2) Also, regarding last week's hw, I'm wondering if my hw was regraded because I didn't see a change with the grades.

Thank you! Happy early Veteran's Day!

For 25 the following diagram might be helpful:

It is a view "cutting" through the diagonal of the square made by the centers of the four spheres with radius $1$.

You HW grade should be updated today.
