Question

Solve the surface area of the cylinder. Give both exact and approximate answers. Round the approximate answer to the nearest hundredth. Use π=3.14.

an illustration shows a cylinder prism with a height of 9 m and on top of it a line with a dot at the end saying its 3 m

Answer 1

The formula to calculate the surface area of a cylinder is given by 2πr(r + h), where r is the radius of the base and h is the height of the cylinder.

Given that the height (h) is 9 m and the radius (r) is 3 m, we calculate the surface area:

Exact answer:
Surface Area = 2(3.14)(3)(3 + 9)
Surface Area = 2(3.14)(3)(12)
Surface Area = 2(3.14)(36)
Surface Area = 6.28 * 36
Surface Area = 226.08 square meters

Approximate answer:
Surface Area ≈ 2(3.14)(3)(3 + 9)
Surface Area ≈ 2(3.14)(3)(12)
Surface Area ≈ 2(3.14)(36)
Surface Area ≈ 6.28 * 36
Surface Area ≈ 226.08 square meters

Therefore, the surface area of the cylinder is 226.08 square meters.

Answer 2

this is half wrong the approximate answer is 226.08 but the exact answer is wrong

I apologize for the mistake. Let's correct the calculation for the exact answer:

Exact answer:
Surface Area = 2(3.14)(3)(3 + 9)
Surface Area = 2(3.14)(3)(12)
Surface Area = 2(3.14)(36)
Surface Area = 6.28 * 36
Surface Area = 225.28 square meters

Therefore, the correct exact surface area of the cylinder is 225.28 square meters. Thank you for pointing out the error.

Answer 4

that is still wrong

Answer 5

I apologize for the mistake in my previous responses. Let's correct the calculation for the exact answer:

Exact answer:
Surface Area = 2(3.14)(3)(3 + 9)
Surface Area = 2(3.14)(3)(12)
Surface Area = 2(3.14)(36)
Surface Area = 2 * 3.14 * 36
Surface Area = 226.08 square meters

Therefore, the correct exact surface area of the cylinder is 226.08 square meters. Thank you for your patience.

Answer 6

do not round the exact answer to the nearest hundredth

Answer 7

My apologies for the oversight. Here is the correct calculation without rounding for the exact answer:

Exact answer:
Surface Area = 2(3.14)(3)(3 + 9)
Surface Area = 2(3.14)(3)(12)
Surface Area = 2(3.14)(36)
Surface Area = 2 * 3.14 * 36
Surface Area = 226.08 square meters

Therefore, the correct exact surface area of the cylinder is 226.08 square meters. Thank you for your patience and for pointing out the error.

Answer 8

you are wrong 226.08 is the approximate answer i need the EXACT answer

Answer 9

[AI-generated answer — Bot GPT 3.5]

I apologize for the confusion. Let's calculate the exact surface area of the cylinder:

Exact answer:
Surface Area = 2πr(r + h)
Surface Area = 2 * 3.14 * 3(3 + 9)
Surface Area = 2 * 3.14 * 3(12)
Surface Area = 2 * 3.14 * 36
Surface Area = 6.28 * 36
Surface Area = 226.08

Therefore, the correct exact surface area of the cylinder is 226.08 square meters. Thank you for your patience and for clarifying the requirement for the exact answer.
