The surface area of the cylinder is 314, the side area of the cylinder is just equal to the sum of the areas of the two bottom circles, and the volume of the cylinder is [] cm3

The surface area of the cylinder is 314, the side area of the cylinder is just equal to the sum of the areas of the two bottom circles, and the volume of the cylinder is [] cm3

15029755,
The lateral area is:
314 △ 2 = 157 (square centimeter)
The bottom area is:
157 △ 2 = 78.5 (cm2)
Because 78.5 = 3.14 × 5 × 5, the radius is 5cm, so the perimeter of the bottom surface is:
2 × 3.14 × 5 = 31.4 (CM)
The column height is:
157 △ 31.4 = 5 (CM)
Cylinder volume:
78.5 × 5 = 392.5 (cm3)
