Answer:
see explanation
Step-by-step explanation:
The wheel has a measure of 360° , thus
360° ÷ 20 ( number of cars on the wheel )
= 18° ← central angle
-------------------------------------
arc length is calculated as
arc = circumference of wheel × fraction of wheel
= 2πr ×
= 2π × 25 × =
≈ 7.85 ft
------------------------------------------
area of sector is calculated as
area = area of wheel × fraction of wheel
= π × 25² × =
≈ 98.17 ft²

The function is
Correct description is the first option with the exception of point (2,0), it should read (2, 0.5)
