Apa jawabanya????????????????????????

22/7 kali 9 pangkat 2 kali 31.5
=8.091

Volume tabung = [tex] \pi [/tex] x r² x tinggi
= [tex] \frac{22}{7} [/tex] x (18 : 2)² x 31,5
= [tex] \frac{22}{7} [/tex] x 9² x 31,5
= [tex] \frac{22}{7} [/tex] x 81 x 31,5
= [tex] \frac{22}{7} [/tex] x 2.551,5
= 8.019cm³

Semoga membantu :)
