Arc Length and Sector Area Formulae
OBJECTIVE :
1. Convert angular measurements
- Define Radian
- Convert measurements in degrees (from 0 Degree to 360 Degree) to Radian vice versa.
- Convert multiple of radians and vice versa.
2. Deduce and use
- The arc length formula s = rθ
- The area of sector formula A= 1/2 rS
3. Apply arc length and sector area formulae to solve a range of work related problems.
Convert from degree to radian:
= x° x ∏/ 180°
Convert from radian o degree:
= y rad x 180°/ ∏
- The area of sector formula A= 1/2 rS
