Given the information in the question, there is no need for any inequality. the flat surface can be described as an equality.
Outer diameter = one and a half inches => outer radius = 0.75 inches.
Inner diameter = three fourths inches => inner radius = 0.375 inches.
Area = pi*(0.752 - 0.3752) square inches.
So one possible set of inequalities is 0 < area < 1,000,000,000 sq inches!
