The formula for the surface area of a sphere is given by 4πr^2, where r is the radius of the sphere.
So, we have the equation 4πr^2 = 7.84(3.14) ft^2.
Dividing both sides by 4π, we get r^2 = 7.84(3.14) / 4π.
Simplifying the right side, we have r^2 = 1.
Taking the square root of both sides gives us r = 1 ft.
Therefore, the radius of the sphere is 1 ft.
