To find the surface area of a cylinder, we need to calculate the sum of the areas of the two circular bases and the lateral surface.
The formula for the surface area of a cylinder is:
Surface area = 2πr² + 2πrh
Given:
Radius (r) = 5 inches
Height (h) = 10 inches
Approximation for pi (π) = 3.14
Substituting the values into the formula:
Surface area = 2 * 3.14 * (5^2) + 2 * 3.14 * 5 * 10
Surface area = 2 * 3.14 * 25 + 2 * 3.14 * 5 * 10
Surface area = 6.28 * 25 + 6.28 * 5 * 10
Surface area = 157 + 314
Surface area = 471 square inches
So, the surface area of the cylinder is 471 square inches.
