The radius is 14.81 units.
The formula for the area of a circle is A = πr^2.
Given that the area is 689, we can set up the equation as follows:
689 = πr^2
Solving for r:
r^2 = 689/π
r = √(689/π) ≈ 14.81
Therefore, the radius is approximately 14.81 units.
The area of a circle is 689 square units, what is the radius?
