Abear was seen near a campground. searchers were dispatched to the region to find the bear.
a. assume the bear can walk in any direction at a rate of 2 miles per hour. suppose the bear was last seen 4 hours ago. how large an area must the searchers cover? use 3.14 for pi. round your answer to the nearest square mile.
b. how much additional area would the searchers have to cover if the bear were last seen 5 years ago?

A. The searchers should cover the greatest area which can be calculated by assuming that the distance covered by the bear for 4 hours is the radius of the circle. 
                                radius = (2 miles/hour)(4 hours) = 8 miles
                             area = 2(3.14)(8 miles)² = 401.92 mi²

B. I would assume that for this number, we are to solve the additional area to be covered if the bear was last seen 5 HOURS ago. 
                                 radius = (2 miles/hour)(5 hours) = 10 miles
                               area = (2)(3.14)(10 miles)² = 628 mi²

We get the answer for B by subtracting the two areas which will give us an answer of 226.08 mi².

The answer would be c
