30+ points
find the missing sector areas and arc lengths.

  see attached

Step-by-step explanation:

The relevant formulas are ...

  s = rθ . . . . . . arc length

  a = (1/2)r²θ . . . . . . sector area

In each case, the angle θ is the central angle in radians.

Arc Length

From smallest to largest, the central angles (in degrees) of the yellow, purple, green, orange sectors are ...

  30°, 50°, 100°, 180°

There are π radians in 180°, so in radians, these are ...

  π/6, 5π/18, 5π/9, π

According to the formula for arc length, the arc lengths will be 6 ft times these values:

  π ft, 5π/3 ft, 10π/3 ft, 6π ft . . . . arc lengths, smallest to largest

__

Area

For area, we need to multiply each of the angle values by ...

  1/2r² 1/2·(6 ft)² = 18 ft²

Equivalently, we can multiply each of the arc lengths by 1/2·r = 3 ft.

Then the sector areas, smallest-to-largest, are ...

  3π ft², 5π ft², 10π ft², 18π ft² . . . . sector areas, smallest to largest
