Answer:

  • 3.84 in

Step-by-step explanation:

The circumference of a quarter is 2.88 in:

  • C/4 = 2.88
  • C = 4*2.88
  • C = 11.52 in

Circumference equation:

  • C = πd

Find the diameter:

  • d = C/π
  • d = 11.52 / 3
  • d = 3.84 in

Find circumference of circle

  • 4(2.88)
  • 11.52in

Now

  • 2πr=11.52
  • r=11.52/6.28
  • r=1.92in

So

diameter=3.84in
