The circumference of the bottom surface is 12.56 meters and the height is 6 meters
The perimeter of the bottom surface is 12.56 meters, the height is 6 meters, and the calculated side area is 12.56 × 6 = 75.36 square meters,
The bottom radius is 12.56 △ 3.14 △ 2 = 2m,
The area of the top and bottom is 2 × 2 × 3.14 × 2 = 25.12 square meters
The surface area is 25.12 + 75.36 = 100.48 square meters
