The area of a circle is 64𝜋 square miles. What is the radius?
A=64𝜋 mi2
To find the radius, we can use the formula for the area of a circle:
A = π * r^2
Given that the area is 64π square miles, we can set up the equation:
64π = π * r^2
Dividing both sides of the equation by π:
64 = r^2
Taking the square root of both sides:
r = √64
Simplifying:
r = 8
Therefore, the radius is 8 miles.
