What is the correct ratio for pi

π = 6.28 2 \pi=\frac{6.28}{2} π = 2 6 . 2 8

π = 2 6.28 \pi=\frac{2}{6.28} π = 6 . 2 8 2

π = 3.14 2 \pi=\frac{3.14}{2} π = 2 3 . 1 4

π = 2 3.14 \pi=\frac{2}{3.14} π = 3 . 1 4 2

Which ratio is correctly representing pi?

3.14 = 12.56 4 3.14=\frac{12.56}{4} 3 . 1 4 = 4 1 2 . 5 6

3.14 = 4 12.56 3.14=\frac{4}{12.56} 3 . 1 4 = 1 2 . 5 6 4

3.14 = 12.56 2 3.14=\frac{12.56}{2} 3 . 1 4 = 2 1 2 . 5 6

3.14 = 2 12.56 3.14=\frac{2}{12.56} 3 . 1 4 = 1 2 . 5 6 2

Which ratio will correctly represent pi?

22 3.5 \frac{22}{3.5} 3 . 5 2 2

3.5 22 \frac{3.5}{22} 2 2 3 . 5

Which ratio will represent pi?

? 2.15 \frac{?}{2.15} 2 . 1 5 ?

Which ratio correctly represents pi?

π = c d \pi=\frac{c}{d} π = d c
