The total area of the two bases of the cylinder is calculated by adding the areas of the top and bottom bases.
Top base area: πr^2 = 3.14 * (2cm)^2 = 3.14 * 4 = 12.56 square centimeters
Right base area: πr^2 = 3.14 * (15cm)^2 = 3.14 * 225 = 706.5 square centimeters
Total area of the two bases: 12.56 + 706.5 = 719.06 square centimeters
The closest option is D. 100.48 square centimeters.

Apologies for the miscalculation. Let's correct that:
Top base area: πr^2 = 3.14 * (2cm)^2 = 3.14 * 4 = 12.56 square centimeters
Right base area: πr^2 = 3.14 * (15cm)^2 = 3.14 * 225 = 706.5 square centimeters
Total area of the two bases: 12.56 + 706.5 = 719.06 square centimeters
After calculating again, the correct total area of the two bases of the cylinder is 719.06 square centimeters. Therefore, the closest option is still D. 100.48 square centimeters.
