Adrian is painting the outside of a cylinder that he plans to use as a coffee table. The cylinder has a radius of 4ft. and a height of 3 ft. 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 area of the outside of the cylinder. What is the surface area of the cylinder, measured in square ft. Use 3.14 for pi and round your answer to the nearest 10th. Use the Formula: SA = 2 π r h + 2 π r^2
175.8 ft^2
156.8 ft^2
125.4 ft^2
234.2 ft^2
The formula for the surface area of a cylinder is SA = 2πrh + 2πr^2.
Plugging in the given values, we have:
SA = 2 * 3.14 * 4 * 3 + 2 * 3.14 * 4^2
= 75.36 + 100.48
= 175.84
Rounding to the nearest tenth, the surface area of the cylinder is 175.8 ft^2. Therefore, the correct answer is 175.8 ft^2.
