Final answer:

The surface area of the cylinder is 75 in², rounded to the nearest whole number.

Step-by-step explanation:

To solve this problem, we need to find the area of a cylinder. The formula for the surface area of a cylinder is A = 2πrh + 2πr², where A is the surface area, r is the radius, and h is the height.

Given that the radius is 2 inches and the height is 4 inches, we can substitute these values into the formula:

A = 2(3.14)(2)(4) + 2(3.14)(2)²

Simplifying the equation, we get:

A = 50.24 + 25.12

A = 75.36

Rounding to the nearest whole number, the answer is 75 in². Therefore, the correct answer is d. 24 in².
