volume sebuah tabung 693cm jika diameter tabung 7 cm tentukanlah tinggi tabung tersebut
Jawaban:
r = D/2 = 7/2 = 3,5 cm
V = Ο × r² × t
693 = 3,14 × 3,5² × t
693 = 38,465 × t
693 : 38,465 = t
18,01 = t
18 cm = t
Jawab:
9 cm
Penjelasan dengan langkah-langkah:
V = PI * 0.25 (d^2) * t
693 cm= (22/7) * (1/4) * (49 cm^2) * t
----------------------------------------------------- (/22)
( 693 / 22) cm^3 = (1/4) * 7t cm^2
31.5 cm^3 = 1/4 * 7t cm^2
------------------------------------------- (*4)
63 cm^3 = 7t cm^2
-------------------------------------------- (/7)
9 cm = t
