SA = 2 +2
+2

1. Find the radius. 
R = 1/2D
6 x 1/2 = 3 
R = 3 
2. Plug them in. 
SA 2(3.14)(3)(7) + 2(3.14)(3^2)
3. Solve
3 x 7 = 21 
21 x 3.14 = 65.94 
65.94 x 2 = 131. 88 
3^2 = 9 
9 x 3.14 = 28.26 
28.26 x 2 = 56.52
4. Add them together. 
131.88 + 56.52 = 188.4 
Answer: 188.4 square millimeters
