Include cubic units. Example r = 3 cm 5 cm Volume = 141.3 cm³ Think: Base area times height: 3.14 \times 3^{2} \times 5 = 141.3 . Given the diameter, halve it first. 1 r = 10 m 8 m Find the volume. 2 r = 2 in 4 in Find the volume. 3 r = 3 m 3 m Find the volume. 4 r = 2 m 4 m Find the volume. 5 d = 6 m 10 m Find the volume. 6 d = 20 ft 4 ft Find the volume.
