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 planet 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 container. What is the surface area of a cylinder, measure in square feet. Use 3.14 for pi and round your answer to the nearest tenth.
The surface area of a cylinder can be found using the formula:
Surface Area = (2πr)h + 2πr^2
where r is the radius and h is the height of the cylinder.
Plugging in the given values:
Surface Area = (2 x 3.14 x 4 x 3) + (2 x 3.14 x 4^2)
Surface Area = (6.28 x 12) + (2 x 3.14 x 16)
Surface Area = 75.36 + 100.48
Surface Area ≈ 175.8 square feet
Therefore, the surface area of the outside of the cylinder is approximately 175.8 square feet.
