Multiple Choice

Solve the problem.
-Earth has a radius of approximately 6400 kilometers, and Venus has a radius of approximately 6500 kilometers (assuming that the planets are spherical) . (i) Compute the surface area and volume for
Both planets. (ii) Which planet has the larger surface-area-to-volume ratio?

A) (i) Surface area of Earth is about 5.15 $5.15 \times 10 ^ { 8 }$ square kilometers, volume of Earth is about
