To find the radius of a circle given its area, we can use the formula:
Area of a circle = π * radius^2
Given that the area is 689 square units, we can rewrite the formula as:
689 = π * radius^2
Let's solve for the radius:
Dividing both sides of the equation by π, we get:
689 / π = radius^2
Taking the square root of both sides, we have:
sqrt(689 / π) = radius
Using a calculator, we can evaluate this to get:
radius ≈ 14.0618
Therefore, the radius of the circle is approximately 14.0618 units.
