The formula for the surface area of a sphere is given by A = 4πr², where A is the surface area and r is the radius of the sphere.

Let's substitute the given surface area into the formula:

7.84π ft² = 4πr²

Now, divide both sides of the equation by 4π:

(7.84π ft²) / (4π) = r²

Simplifying:

1.96 ft² = r²

Finally, take the square root of both sides to solve for r:

r = √1.96 ft²

r ≈ 1.4 ft

Therefore, the radius of the sphere is approximately 1.4 ft.
