I do need help with this problem that includes pi. ^_^
Troyanec [42]

Solution:

<u>Note that:</u>

  • Circumference = 50.24 ft = 2πr = πd
  • Dia. = 16 ft.

<u>Divide the diameter both sides.</u>

  • 50.24 ft = πd
  • => 50.24/d ft = πd/d
  • => 50.24/d ft = π

<u>Substitute the diameter in the equation.</u>

  • => 50.24/16 = π (Option A)
