Question

4) Kevin and his team do not know what direction Mike went when he left the trail. This means that they will have

to search a circular area based on how fast Mike walks. He has been missing for 12 hours and his estimated
speed is 4 km per hour. Determine the surface area of the circle to be searched.​

Answer 1

Explanation:

Distance traveled by Mike in 12 hours = 4 * 12 = 48 km

This will become the radius of the circle

r = 48 km

Area of the circle to be searched = πr²

= 3.14 * 48 * 48

= 7234.56 square km
