Arc length and sector area

What you'll learn

1. Calculate arc length using (theta/360) * 2*pi*r (degrees) and s = r*theta (radians)
2. Calculate the area of a sector using (theta/360) * pi*r^2 (degrees) and A = (1/2)*r^2*theta (radians)
3. Convert between degree and radian measures using the relationship pi radians = 180 degrees
4. Solve multi-step problems that combine arc length, sector area, and central angle relationships
