A cylindrical mug of hot chocolate measures 9.2 cm in diameter and has a height of 12.6 cm. The top 2.5 cm of the mug is filled with whipped cream; the rest is hot chocolate. Rounding to the nearest mL, how much hot chocolate is in the mug? (1 cubic centimeter = 1 liter)

The height of the cylindrical column of hot chocolate is
H = 12.6 - 2.5 = 10.1 cm.
The volume of hot chocolate is
V = pi*(d^2/4)*H
where d = 9.2 cm is the diameter.
V = 67.1 cm^3
That is less than 3 fluid ounces.

I get = 671.4 cm^2
Perhaps DrWls must have missed a decimal place.
