Answer:
3/2-u
Step-by-step explanation:
You need to break the question down by seeing that is it asking for u less than something so that means subtraction. You then see the quotient of 2 and 3 so then you put 3 over 2 to divide and then put your subtract 2 onto it
0.13 hours
468 seconds
7.8 min= 7.8/60= 0.13 hours
7.8 min= 7.8x60= 468 seconds
V = 54π cm³ ⇒ answer (C)
∵ V = (πd²h)/8
∵ d = 6 cm
∵ h = 12 cm
∴ V = (π × 6² × 12) ÷ 8 = 54π cm³
