Studdy Solution
Calculate the arc length for "Under 30 minutes" using the formula $L = \frac{\theta}{360^\circ} \times 2\pi r$:
$$L = \frac{36^\circ}{360^\circ} \times 2\pi \times 4$$ $$L = 0.1 \times 8\pi$$ $$L = 0.8\pi$$
The arc lengths are: a. Over 4 hours: $4\pi$ units b. 1 to 2 hours: $2.4\pi$ units c. Under 1 hour: $0.8\pi$ units d. Under 30 minutes: $0.8\pi$ units
