I’ll do the first one for you
5 x 2 = 10
10pi = around 31.42
You are really just multiplying the diameter by pi, if you are only given the radius, double it first
If you mean 5 7/8, u can rename it to 47/8
Check the picture below, so the square looks more or less like so, since it has all equal sides, then we can simply get the distance of TE and multiply it times 4 and that's the perimeter.
