V 1/2 tabung = 1/2 x π x r x r x t
= 1/2 x 22/7 x 21 x 21 x 90
= 22 x 3 x 21 x 45
= 62370 cm kubik

Answer 2

Verified answer

Diketahui:
t = 90 cm
d = 42 cm

r = 1/2 × d
r = 1/2 × 42 cm
r = 21 cm

Ditanya :
V =

V = 1/2 × V tabung
V = 1/2 × π × r² × t
V = 1/2 × 22/7 × 21² × 90
V = 1/2 × 22/7 × 441 × 90
V = 62370 cm³
