Final answer:
To calculate the surface area of a cylinder correctly, you need to know the specific radius and height of the cylinder and apply the formula A = 2πr(h + r). Without this information, we cannot determine the correct option from a), b), c), or d).
Step-by-step explanation:
To calculate the surface area of a cylinder, we need to use the formula for the surface area of a cylinder, which is given by A = 2πr(h + r), where r is the radius of the circular base of the cylinder and h is its height.
However, since the specific dimensions for the radius and height are not provided in this case, we'll examine the options provided to find the possible surface area:
- a) 4π square units
- b) 6π square units
- c) 12π square units
- d) 20π square units
Without the specific values for radius and height, I cannot confirm which of the options is correct. If the student can provide the radius and height, we could apply the formula and find the accurate surface area.
