volume bangun tsb adalah? a. 1.540 cm³ b. 1.680 cm³ c. 3.080cm³ d. 3.360 cm³

r = 1/2 × d = 1/2 × 14 = 7 cm
Vtabung = phi × r^2 × t
= 22/7 × 7 × 7 × 10
= 1.540 cm³ (a)

Diketahui :
d = 14 cm ,,r= 7cm
t = 10 cm

Ditanya :
Volume tab ?

Jawab :
V tab = πr²t
= 22/7. 7. 7. 10 (7dicrk7)
= 22. 7. 10
= 1540 cm³
