If a section of cylindrical wooden pole is cut into two sections, its surface area will increase by 12.56 square decimeters; If it is split into two and a half cylinders along its diameter, its surface area will increase by 120 square decimeters. How many square decimeters is the surface area of this cylinder?

Bottom diameter multiplied by height: 120 △ 2 = 60 (square decimeter)
The lateral area is 3.14 × 60 = 188.4
Surface area of cylinder: 12.56 + 188.4 = 200.96 (square decimeter)
A: slightly
