the surface area of a sphere is 7.84(3.14) ft^2 what is the radius of the sphere

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.
