Mission to Mars.

On Sunday May 25th, NASA will visit Mars. The goal is to collect soil and ice samples to see if it contains the necessary components for basic life.

1) Mars has a radius of 2,107 miles and Earth has a diameter of 7,900 miles. How many times larger is Earth’s volume than Mars’ volume? Express your answer to the nearest tenth. Note: assume both planets are perfect spheres.  (You may have to look for the formula to calculate the volume of a sphere.)

2) The distance from Mars to the sun can be as little as about 128,390,000 miles (206,620,000 kilometers) or as much as about 154,860,000 miles (249,230,000 kilometers. By what percent does Mars’ distance from the sun increase when it moves from being as close as possible to the sun, to being as far as possible from the sun? Express your answer to the nearest tenth.
