Does the expression 1.016x repersent a percent increase greater than 12% if the original amount is x? rewrite the expression as a sum of two terms to explain why or why not

Let 
x> the original amount

we know that
a percent increase of 12% of x is
  x*[100%+12%]/100> x*[112]/100> x*1.12

1.016x
x*[100%+1.6%]/100> x*[101.6%]/100---> 1.016x
so
1.016x> represent a  percent increase of 1.6% of x

so

the answer is
1.016x is not a percent increase greater than 12%

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
