To find the surface area of a cylinder, we use the formula: SA=2πr^2 + 2πrh.

Given:
Radius (r) = 10 mm
Height (h) = 15 mm
Pi (π) = 3.14

First, calculate the area of each circular base:
Area of one circular base = πr^2
Area of one circular base = 3.14 * (10)^2
Area of one circular base = 314 mm^2

Next, calculate the area of the curved surface (lateral area):
Curved surface area (CSA) = 2πrh
CSA = 2 * 3.14 * 10 * 15
CSA = 942 mm^2

Finally, find the total surface area:
Total Surface Area (SA) = 2πr^2 + 2πrh
SA = 2 * 314 + 942
SA = 628 + 942
SA = 1570 mm^2

Rounding to the nearest tenth, the surface area of the cylinder is approximately 1570 mm^2.

Therefore, the answer is not one of the options given (I.565 mm^3, J.226 mm^3, K.339.12 MM^3).
