Vol 1 = 3.14 x 10.5 x 10.5 x 20 = 6923.7 Vol 2 = 3.14 x 17.5 x 17.5 x 30 = 28848.75 Vol total = 35772.45

A. Tabung V = π × r² × t = 3,14 × 10,5 cm × 10,5 cm × 20 cm = 3,14 × 110,25 cm × 20 cm = 3,14 × 2205 cm = 6923,7 cm³
b. Tabung V = π × r² × t = 3,14 × 17,5 cm × 17,5 cm × 30 cm = 3,14 × 306,25 cm × 30 cm = 3,14 × 9187,5 cm = 28848,75 cm³
Vol 2 = 3.14 x 17.5 x 17.5 x 30 = 28848.75
Vol total = 35772.45
V = π × r² × t
= 3,14 × 10,5 cm × 10,5 cm × 20 cm
= 3,14 × 110,25 cm × 20 cm
= 3,14 × 2205 cm
= 6923,7 cm³
b. Tabung
V = π × r² × t
= 3,14 × 17,5 cm × 17,5 cm × 30 cm
= 3,14 × 306,25 cm × 30 cm
= 3,14 × 9187,5 cm
= 28848,75 cm³
a + b = 6923,7 cm³ + 28848,75 cm³ = 35772,45 cm³
