V. tabung = 9.240 cm³ × r² × t = 9.240 22/7 × r² × 15 = 9.240 330/7 r² = 9.240 r² = 9.240 × 7/330 r² = 196 r = 14 cm

Volum tabung = 9240 phi x r² x t = 9240 22/7 x r² x 15 = 9240 330/7 r² = 9240 r² = 9240 x 7/330 r² = 28 x 7 r = √ 196 r = 14 jawabnya adalah 14
× r² × t = 9.240
22/7 × r² × 15 = 9.240
330/7 r² = 9.240
r² = 9.240 × 7/330
r² = 196
r = 14 cm
phi x r² x t = 9240
22/7 x r² x 15 = 9240
330/7 r² = 9240
r² = 9240 x 7/330
r² = 28 x 7
r = √ 196
r = 14
jawabnya adalah 14
