Sector Area Calculator

Find the area and arc length of a circle sector.

Calculated Output

Sector area 13.09

Arc length 5.236

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

Step-by-Step Breakdown

1. Values used:

2. Radius = 5

3. Angle = 60 degrees

5. Sector area = 13.09

6. Arc length = 5.236

Did this calculator solve your problem today?

The math behind it

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

r 5, 60° → area 13.1, arc 5.24.

Full circle?

At 360° you get the whole circle's area and circumference.
