The side area of a cylinder is 125.6 cents & sup2;, and its height is 8 decimeters. How many square meters is the surface area of the cylinder? The side area of a cylinder is 125.6 decimeters and its height is 8 decimeters. How many square meters is the surface area of the cylinder?

You are brilliant,
Perimeter of bottom surface: 125.6 △ 8 = 15.7 (decimeter)
Bottom radius: 15.7 △ 3.14 △ 2 = 2.5 (decimeter)
Bottom area: 3.14 × 2.5 × 2.5 = 19.625 (square decimeter)
The surface area is: 19.625 × 2 + 125.6 = 164.85 (square decimeter)
