Cylinder Volume Calculator
Calculate the volume of a cylinder using radius and height. Perfect for engineering, manufacturing, plumbing, and packaging applications where you need to determine capacity or material requirements.
Calculate Cylinder Volume
Enter the radius and height of your cylinder:
V = Ο Γ radiusΒ² Γ height
Ο β 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
π² 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.
π Volume Formula
V = ΟrΒ²h
Where Ο β 3.14159, r is the radius, and h is the height
The volume equals the area of the base multiplied by the height
π Surface Area
Total Surface Area = 2ΟrΒ² + 2Οrh
Two circular bases + lateral surface area
Lateral surface area = circumference Γ height
π‘ Pro Tip: The volume formula V = ΟrΒ²h comes from the fact that a cylinder can be "unrolled" into a rectangle with width equal to the circumference (2Οr) and height equal to the cylinder's height. The area of this rectangle equals the lateral surface area.

Special Cylinder Types
π² Right Cylinder
The most common type with bases perpendicular to the axis
Height measured along the axis
All our calculations use right cylinders
π Oblique Cylinder
Bases are not perpendicular to the axis
Height measured perpendicular to bases
More complex volume calculations
π― Hollow Cylinder
Cylinder with a hole through the center
Volume = outer volume - inner volume
Used for pipes and tubes
Engineering Considerations
π οΈ Material Thickness
For hollow cylinders (pipes, tubes)
Inner radius = outer radius - thickness
Volume calculations must account for this
