Hello!</h2>
The answer is:
The total area is:

<h2>
Why?</h2>
To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.
We know that the diameter of each sphere is 7 centimeters, so, calculating we have:
Calculating the radius we have,

Then, calculating the area, we have:


Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.
So, calculating we have:

Hence, the total area is:

Have a nice day!
