Where,
r: sphere radio
Clearing r we have:

Substituting values:

Then, the volume of the sphere is given by:
Substituting values we have:
Answer:
the volume of the sphere is:

7•x=x-15
I think this would work, if I understood what you were saying correctly.
To change a fraction to a decimal , you just divide the number on top by the number on the bottom.
So to change 3/11 to a decimal you divide 3 by 11 and you get 0.272727
= 3/11
= 3 ÷ 11
<span>= 0.272727
