Mathematical Formulas Used in Cone Calculator

The calculator is based on standard geometric formulas for cones.

1. Volume of a Cone

The volume represents the space inside the cone.

Formula:

$V = \frac{1}{3}\pi r^2 h$ V=31πr2h

$r$ r

$h$ h

$A_{\text{base}} = \pi r^2 \approx 28.27$ Abase=πr2≈28.27

$V = \frac{1}{3}\pi r^2 h \approx 75.40$ V=31πr2h≈75.40r = 3.0h = 8.0

Explanation:

π = 3.1416 (approx.)
r = radius
h = height

Example:

Radius	Height	Volume
5	12	314.16

Real-Life Uses:

Ice cream cones
Storage containers
Funnels

2. Base Area of a Cone

The base area is the area of the circular bottom.

Formula:

$A = \pi r^2$ A=πr2

$r$ r

$A = \pi r^2 \approx 28.27$ A=πr2≈28.27

$C = 2\pi r \approx 18.85$ C=2πr≈18.85r = 3.00

Example:

Radius	Base Area
5	78.54

Uses:

Construction planning
Material estimation

3. Curved Surface Area (CSA)

This represents the outer curved surface of the cone.

Formula:

$CSA = \pi r l$ CSA=πrl

Example:

Radius	Slant Height	CSA
5	13	204.20

Uses:

Packaging design
Roofing calculations

4. Total Surface Area (TSA)

Total surface area includes both base and curved surface.

Formula:

$TSA = \pi r^2 + \pi r l$ TSA=πr2+πrl

Example:

Base Area	CSA	Total Surface Area
78.54	204.20	282.74

Example Calculation Table

Here is a complete example using real values:

Parameter	Value
Radius (r)	6
Height (h)	10
Slant Height (l)	12

Result Type	Value
Volume	376.99
Base Area	113.10
Curved Surface Area	226.19
Total Surface Area	339.29
