Sector Area Calculator

Find the area and arc length of a circle sector.

Sector area 13.09
Arc length 5.236

Formula: area = (angle/360) π r² ; arc = (angle/360) 2πr

Step-by-step with your numbers:
1. Values used:
2. Radius = 5
3. Angle = 60 degrees
4.
5. Sector area = 13.09
6. Arc length = 5.236
Did we solve your problem today?

A sector is a 'pie slice' of a circle.

The math behind it

area = (angle ÷ 360) × π × r². Arc length = (angle ÷ 360) × 2πr.

Worked example

r 5, 60° → area 13.1, arc 5.24.
