The statement can be expressed as A = k/r, where k is the constant of proportionality.
To find the constant of proportionality, substitute the given values into the equation:
9 = k/5
To solve for k, multiply both sides of the equation by 5:
45 = k
Therefore, the constant of proportionality is k = 45.
Express the statement as an equation (use k as the constant of proportionality)
A varies inversely as r.
Use the given information to find the constant of proportionality
If r=5,then A=9
K=?
