Question

A ball has a radius of 1 foot. What is the surface area of the ball?

Answer 1

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.

Answer 2

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!
