Question

7 is an unending decimal. Find the

circumference of the circle below using
exact TT
12
C = [?]
C=πd

Answer 1

☞ Question:

• π is an unending decimal. Find the circumference of the circle below using exact π.

☞ Formula for Circumference:

• 
  `\boxed{C = πd}`

☞ Formula for Pie (π):

• 
  `\boxed{π = (22)/(7) \: \: or \: \: 3.14}`

☞ Given:

• π = 3.14
• d = 12

☞ Let's try!

• 
  `C = πd`
• 
  `C = (π)12`
• 
  `C = (3.14)12`
• 
  `\boxed{C = 37.68}`

☞ Answer:

• 
  `\huge\boxed{C = 37.68}`
