Suppose the mean radius of a planet is 6.79 *10^6 m, and that of its moon is 1.80 * 1^8 cm. From these data calculate the following. Recall that the surface area of a sphere is 4pir 2 and the volume of a sphere is below.

(a) Find the ratio of the planet's surface area to that of its moon

(b) Find the ratio of the planet's volume to that of its moon.
