Question

Adrian is painting the outside of a cylinder that he plans to use as a coffee table. The cylinder has a radius of 4 feet and a height

of 3 feet. Adrian wants to paint all around the outside of the cylinder, including the top and bottom faces. In order to understand
how much paint is needed, he wants to know the surface are of the outside of the cylinder. What is the surface area of the
cylinder, measured in square feet? Use 3.14 for pi and round your answer to the nearest tenth.

Answer 1

[AI-generated answer — Bot GPT 3.5]

The surface area of the cylinder is given by the formula:

A = 2πrh + 2πr^2

Where:
A = surface area of the cylinder
r = radius of the cylinder
h = height of the cylinder

Substituting the given values:
A = 2(3.14)(4)(3) + 2(3.14)(4)^2
A = 75.36 + 100.48
A ≈ 175.84

Therefore, the surface area of the cylinder is approximately 175.8 square feet.
