Matematika dik r = 14 cm <br /> t = 20 cm<br />dit ? v ? ​

Matematika dik r = 14 cm
t = 20 cm
dit ? v ?

dik r = 14 cm
t = 20 cm
dit ? v ?

Jwb:

V = phi × r² × t

V = 22/7 × 14cm × 14cm × 20cm

V = 22 × 2cm × 14cm × 20cm

V = 44cm × 14cm × 20cm

V = 616cm × 20cm

V = 12.320cm³

Jadi, volume nya adalah 12.320cm³

Bangun Ruang

Volume Tabung

r = 14 cm

V. tabung = π × r² × t

= 22/7 × 14 × 14 × 20

= 22 × 2 × 14 × 20

= 12.320 cm²
