Answer:
Step-by-step explanation:
let radius=r
height=h
dr/dt=1.6 in/s
dh/dt=-2.2 in/s
volume v=1/3 πr²h
dv/dt=1/3 π[h*2r×dr/dt+r²×dh/dt]
when r=135 in
h=135 in
dv/dt=1/3 π[2×135×135×1.6+135²×(-2.2)]
=1/3 π[135²(3.2-2.2)]
=1/3π135²×1
=6075 π in³/s
The answer is :
24 ml oil
60 g onions
0.36 kg potatoes
0.4 l milk
All you have to do is divide everything by 4.
=3±√5
