Formula

A right circular cone has a circular base and a vertex on the perpendicular axis.

SA = πr(r+l), V = 1/3 πr²h

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter radius and height.
2Click Calculate.

Examples

Cone r=3, h=5

1.l=√34≈5.831.
2.SA≈π×3×8.831≈83.23, V=1/3π×9×5≈47.12.

Result: SA: 83.2297, V: 47.1239

Cone r=4, h=6

1.l=√52≈7.211.
2.V=1/3π×16×6≈100.53.

Result: SA: 140.8820, V: 100.5310

Frequently Asked Questions

SA = πr(r + l), l = slant height.
