Mars has an approximate diameter of 6.794 x 103 kilometers. Assume that Mars is a perfect sphere. Use the formula for the volume of a sphere, V = 4/3 πr3 to determine the volume of Mars. Show your work and give the answer in scientific notation.

solve for r and then plug r into the formula for the volume of a sphere.

well we know that the diameter can also be rewritten as
d=r2
where r=radius and d=diameter
and we know that the only unknown in the formula is r
OpenStudy (anonymous):
Now let's solve for r
2r=d
r=d/2
OpenStudy (anonymous):
so all we have to do is divide the diameter by 2
(6.794 x 103 kilometers)/2=r
OpenStudy (anonymous):
\[\frac{4}{3} πr^3\]
where r=(6.794 x 103)/2
OpenStudy (anonymous):
just plug that in into a calculator and you get the answer for volume
