DIAMETER = RADIUS x 2
CIRCUMFERENCE = π x DIAMETER
DIAMETER = CIRCUMFERENCE ÷ π
AREA OF A CIRCLE = π x (RADIUS)2
Each year, the JPL Education Office creates an illustrated Pi Day math challenge that features real-world problems NASA scientists and engineers solve to explore Earth and space. The 2020 challenge will be available as both a standards-aligned lesson for the classroom and as an activity students can do on their own. Answers will be released Monday, March 16. Explore our collection of lessons and problems from previous years’ challenges at the links below, and check back on March 6 to participate in the 2020 NASA Pi Day Challenge!
