-VOLUME TABUNG-

Volume Tabung = π × r × r × t

V =  × 7 cm × 7 cm × 20 cm

V = 22 × 7 × 20

V = 3.080 cm³

-VOLUME 2 KERUCUT-

Volume 2 Kerucut = 2 × 1/3 × π × r × r × t

V = 2 ×22/7 ×1/3× 7 × 7 × 16

V = 2 ×1/3 × 22 × 7 × 16

V = 1.642,66 cm³

Volume Tempat Pensil Farida = Volume Tabung + Volume 2 Kerucut

V = 3.080 cm³ + 1.642,66 cm³

= 4.722,66 cm³
