The surface area would be 26.5487 m².

The surface area of a cylinder is equal to the area of the circles at both ends, added to the area of the rectangular portion in the middle.  The rectangle in the middle has a width equal to the circumference of the circle and a length equal to the height of the cylinder. 

The circumference of a circle is given by C = πd, and the area of the circles is given by A=πr².  

Since the height is in meters, we will convert it to cm.  3.5 m = 350 cm.
The diameter is 190 cm, so the radius is 190/2 = 95 cm.

This gives us:
SA = 3.14(190)(350)+2(3.14)(95)²
= 208810 + 56677 = 265487 cm² = 26.5487 m²
