First, we need to convert the diameter from centimeters to meters:
130 cm = 1.3 m
Now, we can find the radius of the cylinder:
radius = 1.3 m / 2 = 0.65 m
Next, we can find the surface area of the cylinder using the formula:
Surface area = 2πr(r + h)
Surface area = 2 * 3.14 * 0.65 * (0.65 + 12)
Surface area = 2 * 3.14 * 0.65 * 12.65
Surface area = 25.32 m2 * 12.65
Surface area ≈ 319.88 m2
Therefore, the surface area of the cylinder is approximately 319.88 m2.
Find the surface area of a cylinder that has a height of 12 m and a diameter of 130 cm. Use 3.14 for π
. Round to the nearest hundredth at the last step.
