A would be 54,B would be 54, C would be 65, d would be 61
The length of the band in terms of π is given by the expression:
L = 40mm + π*10mm
<h3>
How to get the length of the band?</h3>
Remember that for a circle of diameter D, the circumference is:
C = π*D.
Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).
because the diameter is 10mm, the length of the band will be:
L = 4*10mm + 4*(π*10mm/4)
L = 40mm + π*10mm
This is the length of the band in terms of π.

See below.
Step-by-step explanation:
The first step could be more complicated if the fractions didn't already have a common denominator.
