In Europe, a large circular walking track with a

diameter of 0.900 km is marked in angular distances in

radians. An American tourist who walks 3.00 mi daily

goes to the track. How many radians should he walk?

Respuesta :

Answer: 10.67

Explanation:

First, we needed to calculate the radius and this will be:

= Diameter / 2

= 0.900km / 2

= 0.450km

Since s = 3.00miles, we need to convert it to kilometers and this will be:

1mile = 1.6km

3 miles = 3 × 1.6km = 4.8km

Radians = s/r = 4.8/0.45 = 10.67
