a. 113.04 miles2113.04 mi l e s squared


b. 59.16 miles259.16 mi l e s squared


c. 37.68 miles237.68 mi l e s squared


d. 18.84 miles2

Answer 1

The area of the circle with a radius of 16.9 miles is approximately 900 square miles.

Step-by-step explanation:

To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle. In this case, the radius is given as 16.9 miles. So, using the value of π as 3.14, we can calculate the area by substituting the given value of r into the formula: A = 3.14 * (16.9)^2.

Calculating this expression gives us an area of approximately 901.7397 square miles. However, since the radius is given with only one significant figure, we need to round our answer to one significant figure as well. Therefore, the circle's area would be approximately 900 square miles.
