This document is designed for a middle or high school math class. It includes the key formulas, step-by-step worked-out answers, common mistakes, and extended practice. ANSWER KEY & Detailed Solutions Essential Formula Reminder The volume ( V ) of a cylinder is given by:

( 500\pi = \pi (100)h ) → ( 500 = 100h ) → ( h = 5 \ \textcm ) ( V = \pi (4)(36) = 144\pi \ \textin^3 ) ≈ ( 452

Radius = 7 cm ( V = \pi (49)(20) = 980\pi \ \textcm^3 ) ≈ ( 3077.2 \ \textcm^3 )

Radius = 3 cm ( V = \pi (9)(10) = 90\pi \ \textcm^3 ) ≈ ( 282.6 \ \textcm^3 ) ANSWER KEY & Detailed Solutions Essential Formula Reminder

[ V = \pi r^2 h ]
