please bantu jawab soal fisika pake cara

_____________________________________________________
Diket :
volume, V = 750π cm³
waktu, t = 3 detik
diameter keran, d = 1,25 cm

Tanya :
kecepatan aliran air yg keluar dari keran, v = __?

Jawab :

Debit,  Q = V/t = A.v
v = V / (A.t)
v = V / (π/4.d².t)
v = 4.V / (π.d².t)
v = 4·750π / (π·1,25²·3)
v =  3000 / (3·1,25²)
v = 640 cm/s

Jawaban : C
