[AI-generated answer — Bot GPT 3.5]

The correct answer is to divide 78.5 by pi and then take the square root of the quotient. This is because the formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 78.5 square feet, we can set up the equation 78.5 = πr^2. By dividing both sides of the equation by pi and then taking the square root of the result, we can determine the value of the radius.
