Best Answer:
Since area = r*r*pi, and we want to find the radius, let's set this up like an equation, using r as the variable that represents the radius (and the value we're looking for). Let's also write it as r^2 (r squared). So the equation looks like this: area = r^2 * pi

We know the area is 2106, and we know that pi is 3.14, so let's plug those numbers in: 2106 = r^2 * 3.14

We know have only one variable, so we can solve the equation! Isolate r by dividing by 3.14: 2106/3.14 = r^2 ----> 670.7 = r^2

Now, so that we can get a value for r, we take the square root of both sides (to negate how we have an r-squared): sq rt(670.7) = r ----> 25.9

That gives us the radius. Since we round to the nearest foot, the answer is 26ft. :)
