Answer:
f(x) = 16x2 + 32x - 9
  
To find the "zeros", set f(x) = 0:
  
     0 = 16x2 + 32x - 9
  
The equation is solvable by factoring or by using the quadratic formula.  The factors (use the "ac" method) are:
  
     0 = (4x-1)(4x+9)
  
     x = 1/4 = 0.25 and x = -9/4 = -2.25

- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>c = 2πr  } => c = πd => d = c/π</em>
<em>2r = d</em>
<em>replace c ; π</em>
<em>π  =3.14</em>
<em>d = 74cm/3.14</em>
<em>= 23.5668</em>
<em>≈ 24 cm</em>
