Answer:
1.406×[tex]10^{[tex]10^{18}km cubed
Step-by-step explanation:
The volume of a sphere is
[tex]V=\frac{4}{3}\pi r^3[/tex]
Filling in our formula:
[tex]V=\frac{4}{3}\pi (695,000)^3[/tex]
Cubing first gives us:
[tex]V=\frac{4}{3}\pi (3.35702[/tex]×[tex]10^{17}[/tex]
Do the multiplication and division of those numbers, multiply in the value of pi on your calculator, and you'll get 1.406×[tex]10^{18}[/tex]
