jika t= 25 cm diameter alas kerucut = 30 cm dan = 22/ 7, tentukan volume kerucut tersebut?

v kerucut = 1/3 phir²t
v = 1/3 x 3,14 x (15)² x 25
v = 1/3 x 3,14 x 225 x 25
v = 5.887,5 cm³

Jari-jari (r) = 1/2 × diameter (d)
Jari-jari = 1/2 × 30
Jari-jari = 15 cm

Volume = 1/3 × 22/7 × r × r × t
Volume = 1/3 × 22/7 × 15 × 15 × 25
Volume = 1/3 × 22/7 × 225 × 25
Volume = 1/3 × 22/7 × 5625
Volume = 1/3 × 17.678,5
Volume = 5892,8 cm3

semoga membantu
