Cone Volume Formula:
| From: | To: |
The volume of a cone is given by \( V = \frac{1}{3} \pi r^2 h \), where \( r \) is the radius of the base and \( h \) is the height of the cone. This formula shows that a cone's volume is exactly one third of a cylinder with the same base and height.
The calculator uses the cone volume formula:
Where:
Explanation: The formula calculates the space occupied by a right circular cone, which has a circular base and a vertex perpendicular to the base's center.
Details: Calculating cone volume is essential in various fields including engineering, architecture, manufacturing, and physics for designing and analyzing conical objects and structures.
Tips: Enter the radius and height in the same units. The result will be in cubic units (units³). Both values must be positive numbers.
Q1: Does this formula work for oblique cones?
A: No, this formula is specifically for right circular cones where the apex is directly above the center of the base.
Q2: What if my cone is truncated (frustum)?
A: For a frustum, you need a different formula: \( V = \frac{1}{3} \pi h (r_1^2 + r_1 r_2 + r_2^2) \), where \( r_1 \) and \( r_2 \) are the two radii.
Q3: How accurate is this calculation?
A: The calculation is mathematically exact for perfect cones. Real-world accuracy depends on measurement precision.
Q4: Can I use different units for radius and height?
A: No, both measurements must be in the same units for the calculation to be valid.
Q5: Why is there a 1/3 in the formula?
A: A cone occupies exactly one third the volume of a cylinder with the same base and height, which is why the formula includes this factor.
