To find the surface area of the cylinder, we can use the formula: A = 2πr^2 + 2πrh
Given:
Radius (r) = 4 meters
Height (h) = 10 meters
π = 3.14 (approximation)
Plugging in the values:
A = 2 * 3.14 * 4^2 + 2 * 3.14 * 4 * 10
A = 2 * 3.14 * 16 + 2 * 3.14 * 4 * 10
A = 100.48 + 251.2
A = 351.68
Therefore, the surface area of the cylinder is approximately 351.68 square meters.
