A criminal has escaped in a train wreck. The police believe he could have traveled no more than 7 mi in any direction from the wreck. How many square miles must be searched

A = 153.94 sq mi

Step-by-step explanation:

In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following

A =

A =

A =

A = 153.94 sq mi

A total of 153.94 square miles must be searched.
