89. Solving a chemistry problem

In a glass tube immersed at one end in water, water rises 2.0 cm at 20 degrees Celsius relative to a flat surface (outside the tube). Calculate the inside diameter of the tube. The density of water is 0.9982 g/cm³, the surface tension is 72.75 mN/m, the contact angle of the glass is 0°. Ignore air density.
