volume sebuah tabung 22.176cm3 jika panjang jari jari 21 cm maka tinggi tabung
![]()
Diketahui:
Volume tabung = 22.176 cm³
r = 21 cm
Ditanya:
tinggi tabung = ... ?
Jawab:
V = πr²t
22.176 = 22/7 × 21 × 21 × t
22.176 = 22 × 3 × 21t
22.176 = 1.386t
1.386t = 22.176
t = 22.176/1.386
t = 16 cm
semoga membantu, semangat belajar!
volume tabung : π × r² × t
22.176 = [tex]\frac{22}{7}[/tex] × 21² × t
22.176 = [tex]\frac{22}{\not7}[/tex] × [tex]\not21^3[/tex] × 21 × t
22.176 = 22 × 3 × 21 × t
22.176 = 1.386 × t
1.386 × t = 22.176
t = 22.176 ÷ 1.386
t = 16 cm
