Determine the radius of the circle given its area. Use 3.14 for π.

A=3.7994 ft^2

The area is A = pi*r^2

We know A = 3.7994ft^2, we know the value for pi.

3.7994ft^2 = pi*r^2

Solve for r.

r=±2.1436???

To determine the radius of a circle given its area, you need to use the area formula for a circle: A = πr^2, where A is the area and r is the radius of the circle.

In this case, you are given the area of the circle as A = 3.7994 ft^2.

So, we can rearrange the formula to solve for the radius:
A = πr^2

Divide both sides of the equation by π:
A/π = r^2

Take the square root of both sides to isolate the radius:
√(A/π) = r

Now, plug in the given area value and the value of π:
√(3.7994/3.14) = r

Using a calculator, evaluate the square root:
r ≈ 1.228 ft (rounded to three decimal places).

Therefore, the radius of the circle is approximately 1.228 feet.
