Question
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. Calculate the surface area of the cylinder without considering the "Lateral Surface Area".
Answers
GPT 3.5
The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Given:
- Radius (r) = 5 inches
- Height (h) = 10 inches
- Approximation for pi (π) = 3.14
Plug in the values:
Surface Area = 2 * 3.14 * 5^2 + 2 * 3.14 * 5 * 10
Surface Area = 2 * 3.14 * 25 + 2 * 3.14 * 50
Surface Area = 157 + 314
Surface Area = 471 square inches
Therefore, the surface area of the cylinder is 471 square inches.
Surface Area = 2πr^2 + 2πrh
Given:
- Radius (r) = 5 inches
- Height (h) = 10 inches
- Approximation for pi (π) = 3.14
Plug in the values:
Surface Area = 2 * 3.14 * 5^2 + 2 * 3.14 * 5 * 10
Surface Area = 2 * 3.14 * 25 + 2 * 3.14 * 50
Surface Area = 157 + 314
Surface Area = 471 square inches
Therefore, the surface area of the cylinder is 471 square inches.
