Unit 8: Pythagorean Theorem, Distance & Volume · NY-8.G.9
Grade 8 State Test
Notes
Formulas on the reference sheet. You will have the Grade 8 formula sheet on the state test. Still practice identifying radius vs. diameter and keeping π until the end unless a decimal is requested.
Vocabulary
radius: The distance from the center of a circle (or sphere) to a point on it.
