Final answer:
To find the surface area of a cylinder, use the formula A = 2πrh + 2πr². Since the height is not given, the exact surface area cannot be calculated. None of the provided options are correct.
Step-by-step explanation:
To find the surface area of a cylinder, you need to find the area of the two circular bases as well as the area of the curved surface. The formula for the surface area of a cylinder is given by:
A = 2πrh + 2πr²
Where:
- A is the surface area of the cylinder
- π is a mathematical constant approximately equal to 3.14159
- r is the radius of the cylinder
- h is the height of the cylinder
Using the given radius of 3, the formula becomes:
A = 2π(3)(h) + 2π(3)²
Since the height is not given, we cannot calculate the exact surface area. Therefore, none of the provided options (75.4, 94.2, 169.6, 226.2) are correct.
