As the radius of the star increases, the mass will also increase.
This is all about the relationship between the radius and mass of stellar main sequence stars.
Now, usually they are expressed in solar units and as such as seen in the graph image attached, the relationship between the radius(R) and mass(M) of a main-sequence star is seen by the curve attached. It is clear that the higher the radius becomes, the larger the mass of the star also becomes.
To clarify this also, we have a mass - lumosity relationship formula where given as;
L = [tex]M^{3.5}[/tex]
Where;
M is mass
L is lumosity
We know from basics of stellar main sequence stars, that a larger radius gives a much brighter lumosity.
From the mass-lumosity formula, we see that Increase in lumosity is directly proportional to an increase in mass. Therefore in the same vein, we can say that increase in radius is directly proportional to an increase in mass.
