Answer:

The best expression represents the value of π is
(37.7)/(12)2nd answer

Explanation:

π is the ratio between the circumference of the circle and the length of its diameter


(C)/(d)=\pi , 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


(C)/(d)=(37.7)/(12)


(C)/(d)=\pi

- Equate the two right hand sides


(37.7)/(12)=\pi

The best expression represents the value of π is
(37.7)/(12)
