To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the volume of a sphere and the formula for calculate the surface area of a sphere, which are:


Where
is the radius (
)
2. The volume is:

3. The surface are is:

The answer are: The volume is
and the surface area is 
5x and 6x are like terms because they are both followed by an x. 20 and -13 are also like terms. For they have nothing behind them. Hope this helps!
