Sin x = 6 ?? Sin x is always between -1 and +1. There is some problem with the question..
Pizza:
1/2 + 1/4 + 1/8 +... 7 terms
sum of Geometric progression : a = 1/2 r = 1/2 n = 7
Sum = a * ( 1 - r^n) / (1 - r) = 1/2 * ( 1 - 1/2^7) / ( 1 - 1/2)
= 127/128 of the pizza
in % it is 12700 /128 % = 99.22%
