To find the surface area of the soup can, we need to find the areas of both the two circular bases and the lateral surface area.
1. Area of the two circular bases:
Area = πr^2
Area = 3.14 x (4 cm)^2
Area = 3.14 x 16 cm^2
Area = 50.24 cm^2
2. Lateral surface area (the curved surface of the cylinder):
Lateral surface area = 2πrh
Lateral surface area = 2 x 3.14 x 4 cm x 11 cm
Lateral surface area = 87.92 cm^2
3. Total surface area of the cylinder:
Total surface area = (area of the two circular bases) + (lateral surface area)
Total surface area = 50.24 cm^2 + 87.92 cm^2
Total surface area = 138.16 cm^2
Therefore, the surface area of the soup can is 138.2 cm^2.
