Question

Find the surface area of the cylinder. Use the formula SA=nr^2+2nrh. Use 3.14 for n . Round your answer to the nearest tenth.
4CM,13CM
1. 301.7 cm^2
2. 140.4 cm^2
3. 500 cm^2
4. 351.7 cm^2

Answer 1

BECAUSE

Answer 2

The correct answer is 351.7 cm^2

Answer 3

The surface area of the cylinder is calculated as SA = 2πrh + 2πr^2, where π ≈ 3.14, r is the radius, and h is the height of the cylinder.

Given that the radius (r) is 4 cm and the height (h) is 13 cm, we can substitute these values into the formula:

SA = 2(3.14)(4)(13) + 2(3.14)(4)^2
SA = 8(3.14)(13) + 2(3.14)(16)
SA = 100.48 + 100.48
SA = 200.96 cm^2

Rounded to the nearest tenth, the surface area of the cylinder is 200.9 cm^2, which was not listed as an option. However, this suggests there may have been an error in the provided answer choices. The closest option to the correct answer is 351.7 cm^2, so that would typically be chosen as the closest or best approximation.
