Find the surface area of a cylinder with a height of 12 meters and a diameter of 14 meters. Use 3.14 for and round to the nearest tenth.
The formula for the surface area of a cylinder is 2πr^2 + 2πrh, where r is the radius and h is the height.
To find the radius, we divide the diameter by 2: 14 meters / 2 = 7 meters.
Surface area = 2 * 3.14 * 7^2 + 2 * 3.14 * 7 * 12
Surface area = 2 * 3.14 * 49 + 2 * 3.14 * 84
Surface area = 308 + 527.52
Surface area = 835.52
Rounded to the nearest tenth, the surface area of the cylinder is 835.5 square meters.
