tolong jawab ini dengan benar
Jawab:
(i) d = 14 cm ---> r = 7 cm
t = 10 cm
V = πr²t
V = 22/7 x (7 cm)² x 10 cm
= 1.540 cm³
(ii) r = 35 cm, t = 25 cm
V = πr²t
V = 22/7 x (35 cm)² x 25 cm
= 96.250 cm³
(iii) d = 21 cm ---> r = 10,5 cm
V = πr²t
9.702 = 22/7 x (10,5 cm)² x t
9.702 = 346,5 x t
t = 9.702 / 346,5
t = 28 cm
