1. The Constant of Proportionality is the ratio between two variables.
2. To find the ratio, you divide one variable by the other variable to get the Constant of Proportionality.
Therefore, to get the constant of proportionality,
let k = Constant of Proportionality
C = C-value from the table
d = d-value from the table
Constant of proportionality (k) = C/d
Choose two sets of ordered pairs from the given table and get the ratios of each ordered pairs:
We’ll take (2, 6.28) and (3, 9.42).
6.28/2 = 3.14
9.42/3 = 3.14
Therefore, the constant of proportionality is k = 3.14.
