The formula for the trigonometric function sin is:
Ф
The side opposite to the ∠g is x, which is equal to 10

the hypotenuse of the triangle is z, which is equal to 11

so the ratio is:

Answer:
<h3> 552.640in³/s</h3>
Step-by-step explanation:
Volume of a cylinder is expressed as;


dV/dr = 2πrh
dV/dr = 2π(4)(6)
dV/dr = 48(3.14)
dV/dr = 150.72in³/m
dV/dh = πr²
dV/dh = 3.14(4)²
dV/dh = 50.24
Given
dh/dt = 5in/s
dr/dt = 2in/s
Substitute into the dV/dt
dV/dt = 150.72(2)+50.24(5)
dV/dt = 301.44 + 251.2
dV/dt= 552.640in³/s
The volume is changing at the rate of 552.640in³/s
I think its around the same time as an average NFL game so probably 2 maby 3 hours long
