Modular arithmetics. Hello !
I’m not experienced with modular arithmetics, so I ask :

Is it possible to make a formula that gives the value of y ?

d is a single digit, and x is a n digit number.

Thank you very much in advance

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
