A storm is expected to hit 7 mi in every direction from a small town. What is the area that the storm will affect ( Use 3.14 for pi)

a. 153.86 square miles
b. 38.47 square miles
c. 43.96 square miles
d. 21.98 square miles

1 answer

b. 38.47 square miles

To find the area of the storm's affect, we need to calculate the area of a circle with a radius of 7 miles.

Area = πr^2
Area = 3.14 * 7^2
Area = 3.14 * 49
Area = 153.86 square miles

However, since the storm affects in all directions, we only need to consider half of the circle's area.

Area = 153.86 / 2
Area = 76.93 square miles

Therefore, the storm will affect approximately 76.93 square miles.
