The surface area of any sphere is    4 π (radius)².

When the radius is 1 ft, the surface area is

                                         4 π (1 ft)²  =  4π ft² .

Answer:

 The surface area of the ball is [tex]4\pi\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of a sphere ( a ball) is equal to

[tex]SA=4\pi r^{2}[/tex]

In this problem we have

[tex]r=1\ ft[/tex]

substitute

[tex]SA=4\pi (1^{2})=4\pi\ ft^{2}[/tex]
