Arc
- Part of the circumference of a circle
- Minor arc = shorter bit
- Major arc = longer bit
- How to find the length of an arc:
- θ/360 x πd
- θ = angle of the arc
- θ/360 x πd
Sector
- A section of a circle
- minor = smaller one
- major = bigger one
- How to find area of a sector:
- θ/360 x πr²
- θ = angle of the sector
- θ/360 x πr²
