Calculate Cylinder Volume

Enter the radius and height of your cylinder:

Cylinder Volume Formula:
V = Ο€ Γ— radiusΒ² Γ— height
Ο€ β‰ˆ 3.14159 (use Math.PI for precision)

Understanding Cylinder Volume

A cylinder is a three-dimensional solid with two parallel circular bases connected by a curved lateral surface. The volume of a cylinder represents the total space enclosed by its surfaces and is calculated by multiplying the area of the circular base by the height.

Cylinder Properties

πŸ”² Cylinder Definition

A cylinder is a three-dimensional shape with two parallel circular bases of equal size connected by a curved surface. The line joining the centers of the two bases is called the axis.

πŸ“ Volume Formula

V = Ο€rΒ²h
Where Ο€ β‰ˆ 3.14159, r is the radius, and h is the height
The volume equals the area of the base multiplied by the height

πŸ“ Surface Area

Total Surface Area = 2Ο€rΒ² + 2Ο€rh
Two circular bases + lateral surface area
Lateral surface area = circumference Γ— height

πŸ’‘ Pro Tip: The volume formula V = Ο€rΒ²h comes from the fact that a cylinder can be "unrolled" into a rectangle with width equal to the circumference (2Ο€r) and height equal to the cylinder's height. The area of this rectangle equals the lateral surface area.

Special Cylinder Types

πŸ”² Right Cylinder

The most common type with bases perpendicular to the axis
Height measured along the axis
All our calculations use right cylinders

πŸ”„ Oblique Cylinder

Bases are not perpendicular to the axis
Height measured perpendicular to bases
More complex volume calculations

🎯 Hollow Cylinder

Cylinder with a hole through the center
Volume = outer volume - inner volume
Used for pipes and tubes

Engineering Considerations

πŸ› οΈ Material Thickness

For hollow cylinders (pipes, tubes)
Inner radius = outer radius - thickness
Volume calculations must account for this

🌑️ Temperature Effects

Materials expand with temperature
Coefficient of thermal expansion
Affects both dimensions and volume
