In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

In this illustrated math problem, students use the mathematical constant pi to find the "habitable zone" around a distant star and determine which of its planets are in that zone.

In this illustrated math problem, students use pi to compare the size of the landing zones for the Mars rovers Curiosity and Perseverance.

In this illustrated math problem, students use pi and physics to calculate how long the Kuiper Belt object Arrokoth takes to orbit the Sun.

In this illustrated math problem, students use pi to measure the water depth of an area mapped by the CORAL mission.

In this illustrated math problem, students use pi to calculate the distance across a disk of debris around the star Beta Pictoris.

In this illustrated problem set, students use pi to determine the size of a Mars dust storm, estimate the water content of a rain cloud, gauge how much Jupiter's Great Red Spot has shrunk and calculate the strength of a laser used to explode ice samples.

In this illustrated math problem, students use the mathematical constant pi to calculate the amount of energy put out by a laser to determine if it can explode an ice sample for analysis.

In this illustrated math problem, students calculate the percent by which Jupiter's Great Red Spot shrank between 1979 and 2018.
