diketahui : v =?
π=22/7
r²= 14—>7cm
t=21cm
bantu kak ​

v = πr² × t

v = 22/7 × 7² × 21

v = 22/7 × 7 × 7 × 21

v = 22 × 1 × 7 × 21

v = 22 × 147

v = 3.234 cm³

Penyelesaian soal :

[tex] \sf v = \pi \times {r}^{2} \times t[/tex]

[tex] \sf = \frac{22}{7} \times {7}^{2} \times 21[/tex]

[tex] \sf = \frac{22}{7} \times 49 \times 21[/tex]

[tex] \sf = \frac{22}{ \bcancel7} \times \bcancel{49} \times 21[/tex]

[tex] \sf = 154 \times 21[/tex]

[tex] \sf = 3.234 \: cm {}^{3} [/tex]
