Right Circular Cone Calculator
What is a Right Circular Cone?
A right circular cone is a three-dimensional geometric shape with a circular base and a single apex directly above the center of the base. The key dimensions used to define a cone are:
- Radius (r): The distance from the center of the circular base to its edge.
- Height (h): The perpendicular distance from the base to the apex.
- Slant Height (l): The distance from the apex to any point on the edge of the base, forming the hypotenuse of the triangle along the cone's side.
From these dimensions, you can calculate:
- Volume: The amount of space inside the cone.
- Surface Area: The total area covering the cone, including the base and lateral surface.
How to Use the Right Circular Cone Calculator
Using our cone calculator is simple and intuitive. Follow these steps:
- Enter the radius: Type the radius of your cone in the "Radius" field. Use decimal values if necessary for precision.
- Enter the height: Provide the perpendicular height of the cone in the "Height" field.
- Click “Calculate”: The calculator instantly displays:
- Volume (units³)
- Slant Height (units)
- Surface Area (units²)
- Reset if needed: Click the “Reset” button to clear inputs and start fresh.
No complex math is required—you’ll get accurate results with just a few clicks.
Formula Behind the Calculator
Although you don’t need to calculate manually, it helps to understand the formulas used:
- Slant Height (l):
l=r2+h2l = \sqrt{r^2 + h^2}l=r2+h2
- Volume (V):
V=13πr2hV = \frac{1}{3} \pi r^2 hV=31πr2h
- Surface Area (A):
A=πr(r+l)A = \pi r (r + l)A=πr(r+l)
The calculator handles all the calculations for you, ensuring precision up to two decimal points.
Example: Using the Cone Calculator
Imagine you have a cone with a radius of 5 units and a height of 12 units.
- Input 5 in the radius field.
- Input 12 in the height field.
- Click Calculate.
The calculator will display:
- Slant Height: 13 units
- Volume: 314.16 units³
- Surface Area: 282.74 units²
This example illustrates how quickly and easily you can get all essential cone dimensions.
