Answer:
The best expression represents the value of π is [tex]\frac{37.7}{12}[/tex] ⇒ 2nd answer
Step-by-step explanation:
π is the ratio between the circumference of the circle and the length of its diameter
[tex]\frac{C}{d}=\pi[/tex] , where
- C is the circumference of the circle
- d is the diameter of the circle
∵ The circumference of the circle is about 37.7 cm
∵ The diameter of the circle is about 12 cm
- Find the ratio between them
∴ [tex]\frac{C}{d}=\frac{37.7}{12}[/tex]
∵ [tex]\frac{C}{d}=\pi[/tex]
- Equate the two right hand sides
∴ [tex]\frac{37.7}{12}=\pi[/tex]
∴ The best expression represents the value of π is [tex]\frac{37.7}{12}[/tex]
