Diameter bola 60 DM , berapa volume bola?
Jawaban:
volume bola = 113.040 dm³
Penjelasan dengan langkah-langkah:
diameter (d) = 60 dm
jari-jari (r) = 60 dm ÷ 2 = 30 dm
V = 4/3 × π × r³
V = 4/3 × 3,14 × 30 dm × 30 dm × 30 dm
V = 4 × 3,14 × 10 dm × 30 dm × 30 dm
V = 12,56 × 9.000 dm³
V = 113.040 dm³
d = 60 dm
r = d/2
r = 60/2
r = 30 dm
Volume bola
V = 4/3 × π × r³
V = 4/3 × 3,14 × 30³
V = 4/3 × 3,14 × (30 × 30 × 30)
V = 4/3 × 3,14 × 27.000
V = 4/3 × 84.780
V = 339.120/3
V = 113.040 dm³
