Math Problem Statement
Find the area of the circle. Use 3.14 for the value of π. Round your answer to the nearest tenth. The radius of the circle is 8 miles.
Solution
The problem is asking for the area of a circle, where the radius is given as 8 miles, and the value of is approximated as 3.14.
Formula for the area of a circle:
Where:
- is the area,
- is the radius,
- is approximated as 3.14.
Substituting the values:
Rounding to the nearest tenth:
Thus, the area of the circle is approximately 201.0 square miles.
