We know that
[volume of a sphere]=(4/3)*pi*r³
r=12 in
[volume of a sphere]=(4/3)*3.14*12³-----> 7234.56 in³------> 7235 in³
the answer is the option
<span>D) 7,235 in</span>³
X=1 or its 10x=10x because you have to add the two 5x's together first the you get 10=10x then divide both sides by 10 you have x=
Answer:
