Verified Answer :

We know, ball is a Sphere.

Surface area of sphere = 4πr²
A = 4 3.14 (1)²
A = 12.56 Ft²

In short, Your Answer would be 12.56 Ft²

Hope this helps!

Answer:

The surface area of the ball is 12.56 square feet.

Step-by-step explanation:

Given : A ball has a radius of 1 foot.  

To find : What is the surface area of the ball?

Solution : Ball is consider as a sphere,

So, The surface area of a sphere is \(S=4\pi r^{2}\)

We have given that radius r = 1 foot

Now, The surface area of the ball is

\(S=4\pi r^{2}\)

\(S=4(3.14) 1^{2}\)

\(S=4(3.14)(1)\)

\(S=12.56 ft^2\)

Therefore, The surface area of the ball is 12.56 square feet.
