After a cylinder with a height of one decimeter is cut into two equal half cylinders, the surface area increases by 60 square centimeters. What is the volume of this cylinder in cubic centimeters?

After a cylinder with a height of one decimeter is cut into two equal half cylinders, the surface area increases by 60 square centimeters. What is the volume of this cylinder in cubic centimeters?

1 decimeter = 10 cm,
Diameter: 60 ﹣ 2 ﹣ 10 = 3cm,
Radius: 3 △ 2 = 1.5cm,
Volume: 3.14x1.5x1.5x10 = 70.65cc
