Hitunglah volume tabung yang memiliki jari jari alas dan tinggi berikut ini a.r=2cm,t=7cm. b.r=4cm,t=20cm. c.r=6cm,t=28cm. d.r=3cm,t=5cm. e.r=3,5cm,t=1,2cm

lewat foto aja ya hehehe

V = π × r² × t
a. 22/7 × 7² × 7
= 22 × 49
= 1078 cm³
b. 3, 14 × 4² × 20
= 31, 4 × 16 × 2
= 1004, 8 cm³
c. 22/7 × 6² × 28
= 22 × 36 × 4
= 1584 cm³
d. 3, 14 × 3² × 5
= 3, 14 × 9 × 5
= 141, 3 cm³
e. 3, 14 × 3, 5² × 1, 2
= 3, 14 × 12, 25 × 1, 2
= 46, 158 cm³
f. 22/7 × 7² × 2, 5
= 22/7 × 49 × 2, 5
= 22 × 7 × 2, 5
= 385 cm³
