Penjelasan: Diketahui tabung Volume (V) ≈ 24.948 cm³ jari-jari ( r ) = 21 cm π ≈ ²²/₇
Ditanya tinggi (t) V = π×r²×t, maka t = V/(π×r²) t = 24.948/(²²/₇×21²) t = 24.948/(²²/₇×21×21) t = 24.948/(22ײ¹/₇×21) t = 24.948/(22×3×21) t = 1134/(3×21) t = 378/21 t = 18 cm
Jawab:
Tinggi tabung = 18 cm
Penjelasan:
Diketahui tabung
Volume (V) ≈ 24.948 cm³
jari-jari ( r ) = 21 cm
π ≈ ²²/₇
Ditanya tinggi (t)
V = π×r²×t, maka
t = V/(π×r²)
t = 24.948/(²²/₇×21²)
t = 24.948/(²²/₇×21×21)
t = 24.948/(22ײ¹/₇×21)
t = 24.948/(22×3×21)
t = 1134/(3×21)
t = 378/21
t = 18 cm
Tinggi tabung = 18 cm
