U6 L3 Surface Area of Cylinders
1. Find the surface area of a cylinder with a radius of 5 inches and a height of 10 inches. Use the approximation 3.14 for pi.(1 point) Responses 314 square inches 314 square inches 471 square inches 471 square inches 345.4 square inches 345.4 square inches 471 inches
1A. 471 square inches
2A. 25.12
3A. 75.36
4A. 94.2 square inches
5A. 477.3 feet^2
To find the surface area of a cylinder, you need to calculate the sum of the areas of the two bases and the lateral surface area.
1. The formula for the surface area of a cylinder is: SA = 2πr(r + h), where r is the radius and h is the height.
Plug in the given values: r = 5 inches and h = 10 inches.
SA = 2 * 3.14 * 5(5 + 10)
= 2 * 3.14 * 5(15)
= 2 * 3.14 * 75
= 471 square inches.
Therefore, the correct answer is 471 square inches (1A).
