Diameter = 6 in, Height = 8 in Radius = 3 in [ V = \pi (3)^2 (8) = \pi (9)(8) = 72\pi \ \textin^3 ] Using 3.14: ( 72 \times 3.14 = 226.08 \ \textin^3 ) Part 2: Practice Problems – Full Answers 1. Radius = 5 m, Height = 12 m ( V = \pi (25)(12) = 300\pi \ \textm^3 ) ≈ ( 942 \ \textm^3 )
Radius = 3 cm ( V = \pi (9)(10) = 90\pi \ \textcm^3 ) ≈ ( 282.6 \ \textcm^3 ) unit volume student handout 1 volume of cylinders answers
( V = \pi (4)(36) = 144\pi \ \textin^3 ) ≈ ( 452.16 \ \textin^3 ) Diameter = 6 in, Height = 8 in
( V = \pi (64)(3) = 192\pi \ \textmm^3 ) ≈ ( 602.88 \ \textmm^3 ) Diameter = 6 in
Radius = 7 cm ( V = \pi (49)(20) = 980\pi \ \textcm^3 ) ≈ ( 3077.2 \ \textcm^3 )
