This is easy bro,
So first, all you have to do is finding the half circumstance,
the formula for circumstance is:
C=π*d
since the diameter is 8, therefore,
C=π*8
C=8π,
using 3.14 for π,

x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = 
= 5
