So the length of the arc is given by: l = r*theta, here theta is the intercepted angle in unit radian
So, 80 degrees = 80/360 * 2pi = 4/9 * pi
So l = r * (4/9 * pi), the constant ratio is 4/9 * pi
Answer:

City 2 has a higher temperature
Step-by-step explanation:
Given


Required
Convert 34°C to °F
Substitute 34 for C in the above formula:



<em>Comparing 93.2 to City 2's temperature of 97; we can conclude that city 2 has a higher temperature</em>
