The variation equation is p = kr^2
<h3>How to determine the variation equation?</h3>
The variables are give as:
Pressure = P
Radius= r
The direct variation from p to the square of r is represented as:

Express as an equation
p = kr^2
Where k represents the constant of variation
Hence, the variation equation is p = kr^2
