jari jari tabung = jari jari kerucut = 7 cm

tinggi tabung = 14 cm, dan tinggi kerucut = (29 cm – 14 cm) = 15 cm , jika π = ²²/7

= volume tabung + volume kerucut

= (πr²t) + (⅓ × πr²t)

= (²²/7 × 7² × 14) + (⅓ × ²²/7 × 7² × 15)

= (²²/7 × 49 × 14) + (⅓ × ²²/7 × 49 × 15)

= (22 × 7 × 14) + (22 × 7 × 5)

= (2.156) + (770)

= 2.926 cm³

Jadi, volume bangun diatas adalah 2.926 cm³

Jawaban:

v=1/3×πr2t+πr2t

=1/3×22/7×7×15+22/7×7×7×14

=462+2156

=2618
