Answer both questions pls!!!!!

A Python-3 code for the problem above is: N=int (input("Enter the value of N: ")) S=0 \# Starting for i in range (0,N+1,1) : print("The summation is", S) Write a new Python- 3 code to estimate PI with the formula: 62=i=1Ni21=1/12+1/22++1/N2 where N is an integer value fed by the user A Python- 3 code for the problem above is: N= int(inputt("Enter the value of N:") S=0#S starting valu for in range (0,N+1,1) : S=S+i \# accumulator print("The summation is", S) Write a new Python 3 code for the problem below for a constant K : S=i=0NK=K+K++K
