Calculation History:

A cone is a three-dimensional geometric shape with a circular base and a smoothly curved lateral surface that tapers to a point called the apex. The height of a cone is the distance from the apex to the base, and the radius of the base is the distance from the center of the base to any point on the circumference of the base.

## Formulae

There are a number of formulae that can be used to calculate the volume, surface area, and lateral surface area of a cone.

• Volume: The volume of a cone is calculated using the following formula:
``````V = (1/3)πr²h
``````

where:

• V is the volume of the cone
• π is the mathematical constant pi, approximately equal to 3.14159
• r is the radius of the base of the cone
• h is the height of the cone

For example, the volume of a cone with a radius of 5 feet and a height of 12 feet is:

``````V = (1/3)π(5 feet)²(12 feet) = 314.16 cubic feet
``````
• Surface area: The surface area of a cone is calculated using the following formula:
``````A = πr² + πrs
``````

where:

• A is the surface area of the cone
• r is the radius of the base of the cone
• s is the slant height of the cone

The slant height of a cone is the distance from the cone’s apex to any point on the circumference of the base. To calculate the slant height of a cone, you can use the following formula:

``````s = √(r² + h²)
``````

For example, the surface area of a cone with a radius of 5 feet and a height of 12 feet is:

``````A = π(5 feet)² + π(5 feet)(√(5 feet)² + (12 feet)²) = 157.08 square feet
``````
• Lateral surface area: The lateral surface area of a cone is calculated using the following formula:
``````L = πrs
``````

where:

• L is the lateral surface area of the cone
• r is the radius of the base of the cone
• s is the slant height of the cone

For example, the lateral surface area of a cone with a radius of 5 feet and a height of 12 feet is:

``````L = π(5 feet)(√(5 feet)² + (12 feet)²) = 125.66 square feet
``````
